S&I 3: Semiconductor Lasers, is an integral part of the Science & Innovations technical program. Dan Wasserman, University of Illinois, Subcommittee Chair provides us with some insight on this year’s invited speakers, hot topics and trends in paper submissions.
Daniel M. Wasserman, S&I 3 Chair, CLEO: 2014
CLEO Team: Can you review the talks that you got and were there any themes or any outstanding trends that you were able to discern?
Dan Wasserman: This was another outstanding year for Semiconductor Laser submissions to CLEO. I think the whole committee was impressed not simply with the quantity of submissions, but more importantly the breadth and quality of these submissions. I think that one of the trends we are seeing in the contributed submissions is a pushing of the accepted state-of-the-art for a wide range of semiconductor lasers, across a broad range of frequencies.
Many of the contributed talks will focus on ‘going big’: record output powers and high efficiency emitters. We are seeing impressive examples of this at long wavelengths (mid-IR and THz) with Watt-level or greater powers, using a range of very clever approaches. At shorter wavelengths, we will have exciting work demonstrating high power VCSELs and photonic crystal lasers. Other talks focus on going small: nano-scale lasers and ultra-fast pulses. Finally, we are very much looking forward to a number of papers focusing on integration of III-V laser materials with Si electronics and photonic integrated circuits.
Overall, S&I 3 will offer an impressive array of contributed talks, with a breadth and quality that is indicative of the very best in current semiconductor laser research.
CLEO Team: Can you tell us a little bit about the Invited & Tutorial Speakers for S&I 3?
Dan Wasserman: We are so honored to have a line-up of truly incredible speakers accept our invitations to present at CLEO: 2014. Our tutorial, entitled “Dealing with Losses in Plasmonics and Metamaterials”, will be given by Professor Jacob Khurgin, from Johns Hopkins University, and will provide insight into a major challenge facing future nano-scale optoelectronics. Anyone who has seen Prof. Khurgin present knows that we are in for a provocative and exciting tutorial! Our invited talks are also quite exciting, and represent a broad cross-section of current cutting-edge semiconductor laser research. Prof. Yoshi Yamamoto (Stanford/Tokyo) will be presenting exciting new results on electrically-driven exciton-polariton lasers and Dr. Richard Stevenson (Toshiba Research) will show the latest results on his group’s demonstration of quantum teleportation using entangled LEDs. Prof. Geert Morthier (Ghent) will provide an overview of his group’s work integrating high-performance micro-lasers onto Si substrates for optical interconnect and logic applications, and Prof. Wolgang Stolz (Philipps University) will discuss his work on near-IR VECSELs grown by MOCVD. Combined, our tutorial and invited speakers will provide an excellent picture of not only the cutting-edge state-of-the-art in semiconductor lasers, but a glimpse into what the future of semiconductor lasers may well look like!
CLEO Team: Are there any talks, in particular, that you are looking forward to hearing? If so, why?
Dan Wasserman: I am, of course, looking forward to all of our talks, it is going to be a very exciting conference this year. That having been said, I am particularly excited to see recent results on high power long wavelength lasers in presentations from the Meyer group at NRL (high power emission from interband cascade lasers), the Botez and Mawst groups at Wisconsin (leaky wave coupling of quantum cascade lasers for high power emission), and the Strasser and Unterrainer groups at TU Wien (demonstrating ~1Watt of power from THz quantum cascade lasers). The demonstration of high power superluminescent emitters, from the Gmachl group at Princeton, will be another exciting presentation. I will also be looking forward to presentations from Prof. Noda’s group (Kyoto) and Prof. Choquette’s group (UIUC) on high power (>1.5W) and coherently coupled photonic crystal lasers, respectively. We are excited to have Prof Matsuo’s group (NTT) present recent results demonstrating electrically pumped photonic crystal lasers integrated onto Si substrates. And finally, I am eager to see a pair of presentations from Prof. Keller’s group at ETH on ultrafast VECSELs and MIXSELs, respectively.
CLEO Team: Thank you very much.
The CLEO Conference, sponsored by APS/Division of Laser Science, IEEE Photonics Society and the Optical Society received record breaking submissions in 2014. The Conference takes place in San Jose, CA, USA, 8-13 June 2014. Visit www.cleoconference.org for program and registration information.
