Advanced Optical Sources for Spectrally Efficient Photonic Systems

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.

Ottawa Life Member Affinity Group presents:Â Ottawa L5, the first integrated Connected & Autonomous Vehicle (CAV) test environment in North America.
The Ottawa L5 private test track is a 1,866 acre, fenced and gated private facility with 16 kilometres of paved roads. The largest secure test facility for CAVs in Canada, the Ottawa L5 private test track creates an ideal proving ground for the safe and productive pre-commercial development, testing, validation and demonstration of CAV technologies. The Ottawa L5 testing facilities are equipped with GPS (RTK), dedicated short range communications (DSRC), Wi-Fi, 4G/LTE and 5G telecommunications and networking infrastructure, making it the first integrated CAV test environment of its kind in North America. Find more information at:Â https://www.investottawa.ca/ottawal5
Tour will last about an hour involving a walk around the site and a group discussion of various technical aspects of the L5 facility. An additional treat is the possibility of an autonomous shuttle ride at the site for some attendees.
Please register in advance with wolfram.lunscher@ieee.org by Friday October 11. Priority will be given to Life members. All members and family are welcome. There is an online liability waiver to be signed. The link will be provided to registrants.

Title of the Talk AI-Powered 5G Networks
& Beyond
Speaker  Hatem Abou-zeidÂ
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.

Seminar Information:
ABSTRACT:
Given the fast pace of innovation in digital health technologies, specifically in relation to the evolution of medical devices with more complex software and increased network connectivity, a new frontier of cybersecurity vulnerabilities has emerged. As a result, designers of such technologies face many challenges and must consider many inter-related factors that contribute to such an insecure environment.
In this talk, we will identify the key classes of vulnerabilities to which modern medical devices and digital health technologies are exposed, discuss the security and privacy challenges in designing these technologies, and outline some of the defensive measures that can address this complex and multi-faceted problem.

![Modern Day Applications of Power Electronics – Who Can Benefit?](https://www.ieeeottawa.ca/wp-content/uploads/2019/11/28Nov-2019-300x192.jpg)
Abstract – Application of power electronics is widespread in everyday
life. Some applications are considered as “nice to have it;†in other cases,
they are essential. This presentation discusses a wide variety of daily-used
applications around the world. Also covered is an advanced topic, such as SMART
Controller that today’s grid requires for voltage regulation, power factor
regulation, unbalance voltage/current regulation, harmonic elimination and so
on. A SMART Controller that is based on functional requirements and
cost-effective solutions is derived from utilizing the best features of all the
technical concepts that are developed until now. Final year students of
electrical engineering undergraduate curriculum, post graduate students,
researchers, academicians and utility engineers will benefit from attending
this course. The participants will hear from an expert who actually designed
and commissioned a few utility-grade SMART controllers since their inception in
the 1990s.
