Ranovus Talk - Quantum Dot Lasers and Silicon Photonics for Co-packaged Optical Engines

Share

We present an overview of Ranovus’ core optical technologies and showcase their application to high-capacity optical interconnects. Specifically, we describe the operation of the Quantum Dot Laser (QDL), which is a comb source of multiple wavelengths provided by a single laser diode. This offers both space and power efficiency benefits in compact optical modules relative to laser diodes that emit a single wavelength. Also, we give an overview of our silicon photonics design portfolio, focusing on the ring resonator modulator and key performance demonstrations of high bitrate modulation and thermal stabilization. We have integrated the QDL and ring resonator modulator to form a compact wavelength-division multiplexed transmitter architecture, which has significant advantages compared to conventional architectures when scaling to higher aggregate bitrates. As the capacity of data center switches will soon face physical limitations in electrical I/O, Ranovus’ high bandwidth-density platform offers a unique solution: it can be deployed as transceivers socketed directly on the server board, providing 3.2 Tb/s optical transport through a combination of wavelength division multiplexing and 100 Gb/s PAM-4 modulation. We will describe the evolution of our optical engines from mid-haul 200 Gb/s pluggable to co-packaged high-capacity optical engines for use inside data centers.

Biography:

Doug Beckett helped start Ranovus Inc. in 2012, and is currently Vice-President, Optical Technologies.  After receiving a PhD from Simon Fraser University, he started his career as a semiconductor laser designer and crystal grower at BNR and Nortel in Ottawa. He then moved to optical transmission system measurement and modeling, relocating to Nortel Harlow, United Kingdom. He was Director of Optical Network Applications and Systems at Ceyba (Ottawa), and subsequently held positions at CoreOptics, Nortel and Ciena.
