Energy efficient integrated photonic systems based on inverse design Jonathan Fan, Jelena Vuckovic, Stephen Boyd (DE-AR0001212)
Our mission is to use data science methods to revolutionize the way photonic systems are
simulated and designed.
❑ Devices can be globally topology optimized through the training of generative neural
networks.
❑ Convolutional neural networks can expedite EM solvers by orders-of-magnitude faster
speeds.

Stanford Photonics INverse design Software (SPINS)
Vuckovic Group - Stanford OTL Docket Number: S18-012
SPINS–B (open source, 3D) on Github, http://github.com/stanfordnqp/spins-b
These WDM devices can be
designed in 3D in a few hours on
gaming GPUs
licensed from Stanford by numerous companies, government and academic labs.

Accelerate optimization by leveraging state-of-the-
art AI hardware/software platforms
Produce photonics designs unattainable by current
techniques:
• performance
• footprint
• yield
• robustness (thermal, alignment, …)
• density (# of wavelengths/modes)
• energy (active devices)
