About This Webinar
As demand for photonic integrated circuits (PICs) expands in and beyond datacom applications, so grows demand for pluggable and co-packaged PIC solutions offering higher levels of laser integration and scalability. Such integration, however, presents both a design and a manufacturing challenge, and will therefore require unified solutions that bridge both phases of PIC development.

OpenLight’s Mader describes an emerging fabrication process, developed in conjunction with Tower Semiconductor, that enables fully integrated lasers on III-V and silicon photonic platforms. The technology achieves high-yield, cost-effective, custom PICs fabricated in end-to-end large-scale manufacturing by leveraging Tower’s BiCMOS process. Key to the success of this process is the development of an open process design kit (PDK) that offers parameterized device cells, fully validated device models, and electro-optic cosimulation capability for high-speed design and validation — all of which lowers the barrier to adopting this advanced technology and shortens the design and product cycle.
