IEEE SSCS Oregon Chapter December Meeting and Seminar (Virtual)
December 10, 2021 @ 8:00 am - 9:30 am
IEEE SSCS Oregon Chapter December Meeting and Seminar Join us for a (virtual) talk from Dr. Sharma of Intel Labs on Friday, December 10th. The seminar will be held from 8:00am to 9:30am (PST) via a Virtual format. Please register for the meeting link and information. Topic: Co-packaged silicon-photonics based optical transceivers for high-speed datacenter interconnects Abstract: Silicon photonics based optical interconnects (I/O) are being explored as a viable alternative to circumvent the reach, bandwidth and power limitations of electrical interconnects for data-centers. Current high-volume products for optical data-center interconnects are in the form of pluggable modules composed of discrete electronics and photonics ICs that plug into server racks. These modules are still limited in energy efficiency due to the relatively long (inches-long) high-speed electrical interconnect between the pluggable module and the XPU. However, recent advances in ultra-compact silicon-based optical modulators and integrated lasers, along with a migration of the interface electronics to densely-integrated silicon processes have led to the development of compact optical I/O modules. These can be collocated on the same package as the XPU (‘co-packaged’) to reduce the length of the high-speed electrical interconnect between the XPU and the optical module to only a few centimeters resulting in advantages in energy efficiency and shoreline bandwidth density. In this talk, I will review prototypes of our silicon-based intensity-modulated optical transceivers and our recent work on scaling optical I/O data-rates at iso-energy efficiency through the use of dense wavelength division multiplexing (DWDM).
