Workshop: Passive Silicon Photonics Fabrication 2024
January 10, 2025 @ 9:00 am - January 12, 2025 @ 6:00 pm
CMC and its SiEPIC partner professors offer this legendary Silicon Photonics Fabrication Workshop starting September 10, 2024.
This workshop is more than a single multi-day workshop. It is an experience that spans one year, includes two design-fabricate-test cycles, and takes place both online and in person.
It begins with a three-month of online activities, including theory on
- Waveguides
- Couplers
- Gratings
- Resonators
The first passive design-fabricate-test cycle is on a shared chip fabricated by ANT nanoSOI technology. The students will experience on
- Modelling of passive components
- Device and circuit design
- Mask layout
- Design review, design for fabrication (DFF) and design for test (DFT)
- Data analysis
This is followed by an in-person workshop (Carleton University, Ottawa, January 10 – 12, 2025, location TBD) focusing on
- Advanced passive photonics design
- AI for photonics design and new devices
- Introduction to the second fabrication run of CMC AMF MPW technology
- Mask layout and verification
The design-fabricate-test cycle takes place over the following six to nine months. The students receive fabricated chips of their designs.
The workshop is intended to bring students to the forefront of research and commercialization in silicon photonics. Siemens and Lumerical (now part of the ANSYS family) support this course by providing access arrangements to their tools.
Important Notes:
- To obtain access to ANT and AMF confidential technology information provided during the course and required for fabrication, your organization must either have active Non-Disclosure Agreements (NDAs) in place or sign new NDAs prior to the release of the information. Please get in touch with Jessica Zhang to facilitate the NDA execution process.
- Workshop participants will have access to other proprietary and confidential information during the course. Each participant is required to sign an Access to Intellectual Property & Non-Disclosure Agreement. Participants should submit a signed agreement to Sarah Neville prior to registration confirmation.
