SC432 - Hands on: Silicon Photonics Component Design & Fabrication

Sunday, 24 March
08:30 - 12:30 (Pacific Time (US & Canada), UTC - 08:00)

Short Course Level: Intermediate


Lukas Chrostowski, University of British Columbia, Canada


Short Course Description:

This short course teaches participants how to model silicon photonic components, design and have fabricated simple passive photonic integrated circuits (PICs) that are experimentally characterized. Numerous companies are presently developing products in applications such as short-reach optical interconnects for data centres. 

We will go through a step-by-step design methodology to design optical filters based on Bragg gratings – specifically, Contra-Directional Grating Assisted Couplers (CDCs) – including identifying target specifications, analytic modeling, designing the photonic component for the chosen parameters, layout for fabrication, and finally, experimental data analysis.

Participant will have one month after OFC to complete their designs.  The fabrication process involves passive-only components, namely waveguides, grating couplers, Bragg gratings, ring resonators, and so on.  Participants will submit their designs, which will be fabricated by a state-of-the-art rapid-prototyping 100 keV electron-beam lithography facility.  All designs will be tested using an automated optical probe station at the University of British Columbia and the data will be provided to the participants. Participants will then analyze their experimental data.

Temporary licenses to Lumerical Solutions and open-source tools will be provided during and after the workshop to complete the design cycle.

Note that the two courses – SC432 and SC454 – can be taken independently or one after the other. 

Short Course Benefits:

This course should enable you to:

  • Model select silicon photonic components.
  • Create compact models for silicon photonic components.
  • Use commercial modelling tools (Lumerical Solutions).
  • Design a basic silicon photonic circuit.
  • Create a silicon photonic layout and submit for manufacturing.
  • Analyze experimental data from real measurements.
  • Compare modeling with real-life experimental results.  
Short Course Audience:

This course is targeted for researchers and students who want to learn how to model and design real silicon photonic components. Familiarity with optics and electromagnetics is a prerequisite.  No previous silicon photonic design experience is required.

Participants shall bring their own laptop computers, with the required software pre-installed.  Licenses and instructions for installing Lumerical Solutions software, and mask layout software, will be provided prior to the course.
