Fully-automated design of grating couplers (software)

Stanford Reference:

18-019

Abstract

Applications

• Designing innovative structures for efficient optical devices
• Examples include silicon photonics components such as power splitters, wavelength demultiplexers, fiber-to-chip grating coupler design, mode converters, metasurface design, quantum circuits (photonic and microwave) LEDs, solar cells, lasers designs

Advantages

• Fully automated and efficient - no human guidance required
• Allows user to ‘design by specification’
• Uses gradient-based optimization methods not derivative-free optimization methods which are computationally inefficient and only work well for small numbers of degrees of freedom
• Resulting designs are significantly more compact, have higher performance, and can potentially realize novel functionalities
• Devices can be easily fabricated by standard lithography techniques
