Synthesis of Candidate’s Career

Focus on Most Significant Contributions

I.Free-Space Optical Communications (FSO)
     Prof. Hai-Han Lu’s most significant contribution is his seminal work on high-speed and long-haul FSO communications. FSO communications, previously limited to moderate bandwidth of a few hundreds of MHz and a short-range of few meters, have been tremendously improved by Prof. Lu using a combination of innovative ideas, like: (i) employing two-stage injection locking technique to significantly enhance the laser-diode transmitter bandwidth, (ii) using multiple-input-multiple-output (MIMO) scheme to improve the free-space transmission capacity, and (iii) incorporating PAM4 modulation with wavelength-division-multiplexing (WDM)/polarization-multiplexing scheme to increase the transmission rate.
     Prof. Lu has been the first to develop high performance WDM FSO communication systems with laser diodes in the visible wavelength range, and also the first to develop high performance MIMO FSO with red-light VCSELs and spatial light modulators. For long-haul free-space transmission, he has introduced tracking and steering technologies to mitigate the laser beam misalignment by turbulence, thus providing a long-haul FSO transmission with high accessibility. The presently achieved performances of 448 Gb/s aggregate transmission capacity and 600-m free-space link are the world record making his approach a new viable technology in FSO communications.
     The impact of the Candidate’s work and relevance to the Nomination category is witnessed by the selected papers (*: Corresponding Author) mostly on OSA Journals, and by the technologies transfer commented below.

[b3]), overcomes the limitations of traditional WiFi transmission systems, and this system has been the subject of a technology transfer to Arno Electro-Optics Co., Ltd (Taiwan), see Ref. [b4].

​

     In addition, the fiber-FSO-5G/6G convergent system has a significant impact for linking fiber-backhaul and optical/RF wireless feeders at comparatively high-speed and long-reach operations. It is an innovative convergence that became the subject of the technology transfer entitled “Fiber-FSO-5G/6G Convergent System”, productively transferred to TS RF Instruments Co., Ltd (Taiwan), see Ref. [b5]. Thanks to the Technology Transfer Programs, all the Companies mentioned above have substantially increased their portfolio of products as well as their revenues.

II.Underwater Wireless Optical Communication (UWOC)

     Prof. Lu’s research on the high-speed and long-range UWOC systems (Ref. [c1] to [c8]) is the second most significant contribution. He has been able to enhance the UWOC state-of-the-art performance of some hundred MHz rates on a few meters distance to multi-Gb/s and several tens of meter underwater link in clear water. He has incorporated in his design several novelties, like light injection and optoelectronic feedback techniques (Ref. [c1]), optical beam reducer/expander (Ref. [c2]), and integration of PAM4 modulation with multi-wavelength polarization-multiplexing (Ref. [c3]). As a first example, the PAM4 UWOC system (Ref. [c1]) employs a light injection and optoelectronic feedback in a blue-light LD transmitter fo`r operation in piped underwater link and outperforms prior UWOC systems reaching 16-Gb/s.

​

     Second, the 25-Gbps UWOC system (Ref. [c4]) has a two-stage injection-locked VCSEL transmitter for operation in high-turbidity underwater link and is presently the world fastest UWOC link. For long-range free-space plus underwater links, the Candidate has developed systems employing low-cost optics, plastic optical fiber (POF), and optical beam reducer (Ref. [c5]) to attain a long-range free-space in series with the underwater link. The presently achieved performance of 500 Gb/s aggregate transmission rate over a 110 m free-space and 10-m underwater distance is the world record of UWOC systems, as described in his Invited Paper presented at OFC 2018 (Ref. [c3] and [c6]).

​

     About product development, the high-speed PAM4 UWOC link (Ref. [c1]) has led to the technology transfer entitled “A 16-Gb/s High-Speed PAM4 UWOC Link” (Ref. [d1]), beneficiary the Agilelink Technology Co., Ltd. (Taiwan), who since then has been the first company to fabricate and sell a high-performance UWOC system. Agilelink Technology utilized this technology to manufacture LD-based mini submarine and became an ODM of LD-based mini submarine (see https://www.cool3c.com/article/106145).

​

     The technology of light injection and optoelectronic feedback of the 25-Gb/s/10-m PAM4 UWOC system (Ref. [c4]) has also resulted in an industry-academia collaboration with Samwell Testing Co., Ltd. (Taiwan), entitled “A 25-Gb/s/10-m PAM4 UWOC System” (Ref. [d2]). Thanks to this program, the company is now manufacturing LD-based UWOC ship-and-diver links and has become an ODM supplier of UWOC (see https://www.youtube.com/watch?v=ynn9ORQewEE).

​

     With the help of the Technology Transfer Program and Industry-Academia Collaboration, the Companies mentioned above have substantially increased their portfolio of products as well as their revenues.

Conference Leadership Positions

Developing solutions for free-space or underwater optical links may appear at first sight just an exercise of engineering design, not at all a great discovery. But this Nominator – an IEEE Life Fellow and OSA Meritorious Fellow – wishes to point out that the Candidate has added genuine science to his excellent design ended in several real-world products. So, while I could ever identify him as “5-Technical Leadership”, category in which he would certainly deserve elevation to Fellow, I want to recognize he has really significantly contributed to the advancement of Optical Science, and merits the category “3- Engineering, Application and Development” or even the 4-Engineering and Science Research” as I have matured belief on reading and preparing  this nomination – by myself and not with the participation of the Candidate - as recommended by the OSA Guide to Nominations.​

        Prof. Hai-Han Lu earned a PhD in Electro-Optical Engineering from the Institute of Electro-Optical Engineering, National Central University, Taiwan, in 2000. He has served as Chair of the Department of Electro-Optical Engineering at the National Taipei University of Technology (NTUT) and Vice President of Tung-Nan University from 2005-2008 and 2011-2013, respectively. Currently, he is a Life Distinguished Professor in the Department of Electro-Optical Engineering at the NTUT.

       Contributions of the candidate are in the field of optical communication technology, and have been carried out at NTUT, a University with a strong commitment to technology and engineering, similar to Polytechnic Universities in Europe, for this reason also identified as TaipeiTech.  Pursuant to this mission, the candidate has been able to provide remarkable conceptual advancements, but even more important, he constantly endeavored to translate them into viable engineering solutions and work out results ending in a technology transfer to the optical communication industry in Taiwan. He has currently at his credit twenty-seven successful transfers of research pre-products to companies active in optical communication and telecommunications, carried out under the aegis of the MOST (Ministry of Science and Technology).

       In the early years of his career, Prof. Lu focused on optical transmission systems short-haul cloud and local area network, and developed many innovative solutions for applications in fiber-optic CATV, radio-over-fiber, high-speed data transmission, and convergence of broadband services like analog CATV, BB, MW, and MMW signals over hybrid lightwave subcarrier transmission, and the results were transferred with a dozen "Technologies Transfer" or " Industry-Academia Collaborations " in favor of Companies like Agilelink Technology, Chin-Cheung Enterprise, Cable-Giant CATV, TS RF Instruments, Yu-Yi Enterprise, and Lian Jue Technology (see p. 8, Technologies Transfer TT9, TT10, TT13).

       The more recent and most important subjects of study of the candidate have been the free-space optical (FSO) communications and the underwater wireless optical communication (UWOC). A focus on these researches is reported in next Section, and here we summarize motivations and achievements.

       Prof. Lu has been visionary in starting very early experiments demonstrating that free-space is another channel, additional to the traditional guided-wave, offering multi-Gb/s capacity and amenable to indoor and short-distance connections. His first achievement in 2014 was an 8-channel 12.5 Gb/s FSO communication with a total capacity of 100 Gb/s. For the first time, FSO communications are adopted to replace cables/fibers among cloud servers in a data center.

       In developing high-performance FSO communications, prof. Lu has been the first to develop a 448-Gb/s PAM4 FSO communication through 600 m free-space link, demonstrating an 8x increase of aggregate data rate. Another crucial innovation he has introduced for high-speed free-space transmission is the tracking and beam steering technique to mitigate turbulence. The presently achieved performances of 800 Gb/s aggregate transmission capacity and 200 m free-space link are the world record making his approach a new viable technology in FSO communications.

       Sharing much of the technology of FSO communications in underwater links is another subject of study, the UWOC systems concurrently developed by the candidate. Prof. Lu was the first to demonstrate 25 Gb/s transmission in high-turbidity underwater link using a two-stage injection-locked VCSEL transmitter. The 25 Gb/s transmission rate is presently the world fastest UWOC link and this technology has been transferred to a Company and incorporated in a product. For applications requiring a long-reach free-space in cascade to an underwater link, the Candidate has developed a system employing PAM4 modulation with polarization-multiplexing scheme to attain 500 Gb/s of aggregate transmission rate over a 110-m optical wireless link, the world record described in his invited paper presented at OFC 2018. Worth noting, two of his papers in FSO (Optics Express, 2012) and UWOC (IEEE Photonics Journal, 2016) reported record downloads and citations.

       A distinctive feature of Prof. Lu’s activity has been the support to technology transfers and industry-academia collaborations, see below the list TT1-TT15 and IAC1-IAC12 (see p. 8-9). These programs helped Companies to translate successful technologies into products. Just to cite two examples: (i) the “A 100-Gbps Ultra-High-Speed FSO Communication” has been transferred to Hold Precision Technology Co., Ltd., a high-tech Taiwan company, that has then become an ODM supplier of FSO communication transceiver, and (ii) “A 25-Gb/s/10-m PAM4 UWOC System an industry-academia collaboration program for Samwell Testing Co., Ltd, a company since then becomes an ODM of LD-based UWOC systems.

       At the National level, he has served as Consultant for 4G/5G Mobile Telecommunication and digital CATV Committees of National Communications Commission (NCC), responsible for Taiwan’s national 4G/5G mobile telecommunications and digital CATV standards.

       Prof. Lu has published extensively on OSA and IEEE Journals, totaling more than 200 peer-reviewed journal papers, 140 papers in international conferences proceedings and deposited 14 patents (see page 6-8). He has received a dozen Awards from National Associations (see p. 9) and volunteered in scientific Societies in the position of Associate Editor of IEEE Photonics Journal (2017-2020) and SPIE Optical Engineering (2012-present), and also as Chair or Member of Steering Committee, Technical Program Committee, and Invited Speaker of premiere international conferences (in the last three years: WOCC 2021, IPC 2021/2020, OECC 2020, OFC 2018 and CLEO-PR 2018). He also serves as Counsellor of the IEEE Student Branch at NTUT.

       The Candidate has also an important record of teaching activity and University managing. He has been the Vice-President of Tung-Nan University (2011-2013) and was appointed Distinguished Professor of NTUT in 2006 and Lifetime Distinguished Professor in 2013. He actively fostered educational issues, devising new courses in optoelectronics and writing two well-known textbooks (BCB3 and BCB4 on p. 8) that have been used over a decade for training of engineers and technicians in Taiwan on fiber optics and CATV.

       His educational efforts culminated in founding of the Department of Electro-Optical Engineering at NTUT. The Department, located in a 5-stories building and now totaling 24 staff and 200 students, has been headed by the candidate and operated in connection with Taipei Tech, the spinoff of NTUT for technology transfer, of which he is also a promoter. Also remarkable is the care he devotes in tutoring his Master students, a dozen-people group, grown up and mentored day by day in research.
