SC432 - Hands on: Silicon Photonics Design & Fabrication

Monday, 21 March
08:30 - 12:30

Short Course Level: Intermediate

Instructor: Lukas Chrostowski1, Chris Doerr2;  1University of British Columbia, Canada;  2Acacia Communications, USA


Short Course Description:

This short course teaches participants how to design silicon photonicintegrated circuits (PICs), and have a PIC that they designed actually fabricated and characterized, each year will have a different foucs, this year being on resonators and pliarization splittin grotators. Numerous companies are presently developing products in applications such as short-reach optical interconnects for data centres.  Ring resonators / ring modulators are receiving significant attention due to their small size and low power consumption.  Polarization diversity is required in most applications, and polarization components such as splitters and rotators are required. 
We will go through a step-by-step design methodology to design ring resonators, including identifying target specifications, analytic modeling, photonic circuit modeling for choosing parameters, waveguide modeling, directional coupler design, manufacturing variability analysis, design of experiment, layout for fabrication, and finally, experimental data analysis.
We will then go through the design methodology for a polarization splitting rotator based on sub-wavelength grating (SWG) waveguides.  This will include calculating the band-structure diagrams of SWG waveguides, using the effective medium theory to simulate a polarization rotating directional coupler, verifying our design using 3D-FDTD, designing the experiment, and creating a layout.
Participant will have one month after OFC to complete their designs.  Participants will submit their designs, which will be fabricated by a state-of-the-art rapid-prototyping 100 keV electron-beam lithography facility at the University of Washington. 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.
Short Course Benefits:

Participation includes access to commercial modeling tools, fabrication, and measurements.  Students will thus be able to compare their 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 silicon photonic  real components. Familiarity with optics and electromagnetics is a pre-requisite, as well as general knowledge of photonic integrated circuits.  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 MODE, FDTD, and INTERCONNECT, and mask layout software, will be provided prior to the course.
