OptiFabric: Open-Source Photonic IC Design Software

Design and optimize photonic integrated circuits with OptiFabric, an open-source software for waveguide pattern layout, simulation, and optimization.

What is OptiFabric?

OptiFabric is an open-source photonic IC design software developed by researchers at MIT and the University of Washington. It provides a complete framework for designing, simulating, and optimizing silicon photonics devices and circuits.

Some key features of OptiFabric include:

• User-friendly graphical editor for drawing waveguide layouts and placing photonic components
• Python-based scripts and APIs for programmatic circuit design
• Rigorous simulation engines for modeling waveguide propagation, fiber coupling, and component behaviors
• Integrated optimization tools like genetic algorithms and adjoint techniques to automate the improvement of circuit performance
• Model libraries for common passive and active photonic devices
• Support for multi-project wafer tapeout and process design kits from multiple foundries

By providing both flexibility for designers and automation for improving designs, OptiFabric aims to streamline and accelerate the development of novel, manufacturable photonic integrated circuits and systems.

The software is actively developed on GitHub by a team of researchers at MIT, University of Washington, and other contributors from industry and academia. It continues to expand in capabilities and user base as a platform for IC photonics research and development.
