Advanced Optical Sources for Spectrally Efficient Photonic Systems
Liam Barry,
Dublin City University

 

Abstract

The continuing growth in demand for bandwidth (from residential and business users), necessitates significant research into new advanced technologies that will be employed in future broadband communication systems. Two specific technologies which are becoming increasingly important for future photonic
systems are wavelength tunable lasers and optical frequency combs. Although these topics have been studied for over two decades their significance for the development of future ultra-high capacity photonic systems has only recently been fully understood. Wavelength tunable lasers are currently becoming the
norm in optical communication systems because of their flexibility and ability to work on any wavelength. However, as their operating principles are different to standard single mode lasers they can effect how future systems will operate.

For example as optical transmission systems move towards more coherent transmission (where the data is carried using both the intensity and phase of the optical carrier), the phase noise in these tunable lasers will become increasingly important. Optical frequency combs also have many applications for
future photonics systems, and for telecommunications they can be used to obtain the highest spectral efficiency in optical transmission systems by employing the technology of optical frequency division multiplexing (OFDM) that has been widely employed to increase spectral efficiency in wireless systems. Wavelength tunable lasers and optical frequency combs are thus topics at the leading edge of current photonics systems research, and their detailed understanding promises new applications in all-optical signal processing, optical sensing and metrology, and specifically telecommunications. This talk will focus on the development and characterization of various wavelength tunable lasers and optical frequency combs, and then outline how these sources can be employed for developing optical transmission systems and networks which make the best use of available optical spectrum.

Title of the Talk AI-Powered 5G Networks
& Beyond

Speaker  Hatem Abou-zeid 

Summary

5G Networks are anticipated
to transform modern societies by providing an ultra-reliable, high-speed
communications infrastructure that will connect billions of devices including
vehicles, machines, and sensors. Both the complexity of such networks and the
diversity of application requirements will be unprecedented. This mandates
novel, autonomous network configuration and operation that can anticipate and
react to changes in traffic, topology, and interference conditions to ensure
seamless quality of experience and reliability. In this talk I will discuss
AI-driven networking use-cases elaborating on the practical challenges of
industrial deployments. I will then highlight directions where research is
needed to further expedite and facilitate the development of AI-powered
networks.

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 1988, he joined NTT Optoelectronics Laboratories, Atsugi, where he was engaged in research on photonic functional devices using MQW-pin modulators and VCSELs. In 1997, he researched optical networks using WDM technologies at NTT Network Innovation Laboratories, Yokosuka. Since 2000, he has been researching InP-based photonic integrated circuits including fast tunable lasers and photonic crystal lasers at NTT Photonics Laboratories, Atsugi.

IEEE CANADA TECHNOLOGY LEADERSHIP WEBINAR SERIES – II
May 21 @ 14:00 – 15:00

Speaker: Suzanne
Grant of Canadian Advanced Technology Alliance

Topic: #TechnologyNorth – the gold standard

Suzanne envisions a world where a Made in Canada #TechnologyNorth seal is the global gold standard of quality, synonymous with leather shoes Made in Italy, grapes harvested in Champagne, and autos designed and manufactured in Germany. Canada’s world class innovators have delivered excellence decade over decade. Without adequate support of the sector through COVID19, this vision may be a non-starter. During economic difficulties Canada has traditionally bailed out traditional auto and airline industries, and innovative technologies like the AVRO Arrow, Nortel, Research In Motion, Cognos and aspiring young companies were orphaned. By failing to protect our  innovators, Canada traded in future traction of Canada’s valuable intellectual property. America, Europe and the Middle East hungry to prosper from our bargain IP and talent came out the winners. Each downturn has taken at least a decade for technology to reinvent itself and rebound.

We have a track record of great beginnings and a more mature Canada can weather the storms and aim for bigger commercial finish lines, where prosperity and job abundance translate to big returns. Before COVID19 struck, we were hitting our stride with record venture investments and sought after talent from leading education institutions. Canada’s Innovation Agenda demonstrated a maturing future view aiming to lead. This is no time to retreat! The government has invested on behalf of Canadians and accountable for a $36B year over year injection into innovation via universities and commercialization. This investment is at risk. Toronto was the fastest growing tech hub in North America with ICT and advanced technologies outpacing job and economic growth rates by almost twice the national average. As we look beyond COVID19, our technology sector, adequately supported through this crisis, can be the catalyst to jump start Canada’s future economy. With a troubled oil and gas sector, Canada will need agile, fast movers doing the heavy lifting to fund our social, health and education programs and rebuild the nation’s balance sheet.

And as we get back to shipping products and services, a more sophisticated approach to sales, branding, advocacy and public relations, layered with Canada’s science, technology, engineering and maths genius can place Canada out in front in multiple lanes. The digitization revolution just got a bump up and opportunities and demand will remain for trillion dollar market frontiers. Data, Internet of things and machine learning are golden.  Demand for artificial intelligence, environmental, medical and space solutions will continue to accelerate. Winning the future will take more collaboration, agility, commercial savvy and embracing diverse talent sets and creativity. We’ve got this Canada!
