OIDA Sponsored Webinar: Migrating a PIC Simulation to a System Design: Silicon-Photonic Modulator in a PAM-4 Link

2 June 2020, 11:00 - 12:00 - Eastern Daylight Time (UTC - 04:00)

Modeling and simulation at both the circuit- and system-levels are critical in the design process for optical communication, quantum key distribution and sensing applications. Seamless migration between these two levels of abstraction will be demonstrated in VPIphotonics Design Suite. This webinar will focus on an optical communication application example by modeling a silicon-photonic modulator at the circuit-level and implementing it for simulation at the system-level in a PAM-4 link.

Dr. Jim Farina, US Managing Director/Director of Technical Services, VPIphotonics

Jim Farina has a 40-year history of work in optics in a variety of areas. He began his career working in quantum optics researching topics such as optical bistability, 2-photon amplification and partially coherent optical sources. Upon joining the United Technologies Research Center, he was engaged in developing ultra-long wavelength lasers, GaAlAs devices and eventually LiNbO3 modulator development. He was cofounder of two startups in the 1990’s involving the manufacture of LiNbO3 modulators and their application. Since 2004, he has been involved with VPIphotonics in the system and device modeling areas. Jim graduated with a BSEE degree from Worcester Polytechnic Institute and a PhD in Physics from Drexel University. Currently, he is the Managing Director of VPIphotonics’ North American operations.
