Abstract / Description: 

The goal of this workshop is to provide attendees with a practitioner's perspective of the basic ingredients and tools of inverse design using SPINS [1], a photonic optimization framework developed at Jelena Vuckovic's Nanoscale and Quantum Photonics Lab over the past decade.
SPINS is a flexible inverse-design platform that is compatible with a variety of device parametrizations, electromagnetic solvers, and objective functions. This has enabled SPINS to be used to design and experimentally demonstrate functional devices in a wide variety of different application areas including grating couplers [2-4], optical routing for LiDAR [5], and electron accelerators [6].
In this workshop, we will work through examples of using SPINS to design simple devices, including grating couplers and silicon photonics devices. We will emphasize how attendees can adapt these examples for their own applications and discuss some practical considerations for using inverse-design to produce functional devices. All example code will be available online after the workshop.
