Advanced semiconductor lasers:Ultra-low operating energy and heterogeneous integration with Si photonics devices

Shinji Matsuo, NTT Photonics Laboratories, Japan

Abstract: The electrical power consumed in data transmission systems is now hampering efforts to further increase the speed and capacity at various scales, ranging from data centers to microprocessors. Optical interconnects employing an ultralow energy directly modulated lasers will play a key role in reducing the power consumption. Since a laser’s operating energy is proportional to the size of its active volume, developing high-performance lasers with a small cavity is important. For this purpose, we have developed membrane DFB and photonic crystal (PhC) lasers, in which active regions are buried with InP layer. Thanks to the reduction of cavity size and the increase in optical confinement factor, we have achieved extremely small operating energy and demonstrated 4.4-fJ/bit operating energy by employing wavelength-scale PhC cavity. Reduction of the cost is also important issue because huge number of transmitters are required for short distance optical links. For this purpose, Si photonics technology is expected to be a potential solution because it can provide large-scale phonic integrated circuits (PICs), which can reduce the assembly cost compared with transmitters constructed by discrete devices. Therefore, heterogeneous integration of III-V compound semiconductors and Si has attracted much attention. For fabricating these devices, we have developed wafer-scale fabrication procedure that employs regrowth of III-V compound semiconductors on directly bonded thin InP template on SiO2/Si substrate. A key to realize high-quality epitaxial layer is total thickness, which must be below the critical thickness, typically 430 nm. Thus, membrane structure is quite suitable for heterogeneous integration. I will talk about our recent progress, focusing on ultralow-powerconsumption directly modulated lasers and their photonic integrated circuit. I will also describe progress in heterogeneous integration of these lasers and Si photonics devices.

In 2014, he was elected as a Fellow of the Canadian Academy of Engineering (CAE) in recognition of his significant contributions to the field of engineering. He has been named five times to the Global Telecoms Business magazine’s GTB Power 100, a list of the 100 most powerful and influential people in the telecoms industry.

Ibrahim served in many IEEE executive and leadership posts on the Society, Region, Section, and Chapter level. He is currently the Senate Chair of IEEE Ottawa Section, the Industry Advisor of the IEEE Communications Society for the North America Region, and the Industry Advisor for the IEEE Consumer Electronics Society. Ibrahim is very well known a keynote speaker, he organized and hosted several national and international conferences. He was the General Chair of the 2012 IEEE International Conference on Communications – ICC2012 (IEEE Communications Society’s flagship conference), and he is currently the General Chair of the 2021 IEEE International Conference on Communications – ICC2021 that will be held in Montreal on June 14-18, 2021. He received many awards, just to name few, the Consumer Electronics Society’s Distinctive Exemplary Industry Leader Award in 2019, and the IEEE Canada’s Outstanding Canadian Engineer Award in 2001.

On behalf of the conference organizing committee,
we invite you to the virtual Photonics North Conference on May 26-28,
2020.  In the midst of a global crisis,
we look forward to meeting with all of you, our colleagues, as we carry on with
the work of advancing optical science and engineering. Join us for outstanding
plenary talks from inspirational thought leaders. Join us for the very best
work from respected and established researchers. Join us for talks from
emerging researchers, presenting what is surely the opening work of brilliant,
burgeoning careers.

Photonics and optics are finally seeing widespread adoption and significant growth into new markets. Photonic devices are being applied to sensing, communications, and even quantum computing. High speed fiber optics and highly integrated subsystems are essential to the rollout of 5G systems. There has never been a better time for research, development, and training in photonics and Photonics North is essential for developing and promoting the ecosystem.

IEEEXtreme is a worldwide Annual Hackathon, in which teams of IEEE student members participate against each other in a span of 24 hours to solve a set of programming problems. This year IEEEXtreme 14.0 is being held on October 24th. Ragunath Anbarasu, the web master and an active volunteer of IEEE WIE Ottawa has been selected as the Ambassador and Section Lead for the Ottawa region. In this session, he will walk through the IEEEXtreme competition and WIE HACK613, a mock hackathon IEEE WIE Ottawa is organizing as a practice for IEEEXtreme. Register Now! And learn more about the event!

Bio: Ragunath Anbarasu is currently doing his Masters in Electrical and Computer Engineering with Specialization in Data Science at Carleton University. He as been the Web Master of IEEE WIE Ottawa for almost a year and is extremely active in volunteering activities related to IEEE. He has been coordinating with the organizers in hosting this years IEEEXtreme Programming Competition in their respective student branches and supporting Non-IEEE Student Branch Members to get exposure to the Hackathon. He will be extending his help to students looking for support and guidance with information related to IEEEXtreme and connect them to a professional member.
