neuroptica is a flexible chip-level simulation platform for nanophotonic neural networks written in Python/NumPy. It provides a wide range of abstracton levels for simulating optical NN's: the lowest-level functionality allows you to manipulate the arrangement and properties of individual phase shifters on a simulated chip, and the highest-level features provide a Keras-like API for designing optical NN by stacking network layers.
The easiest way to get started with neuroptica is to install directly from the Python package manager:
pip install neuroptica
Alternately, you can clone the repository source code and edit it as needed with:
git clone https://github.com/fancompute/neuroptica.git
pip install -e neuroptica
To run unit tests, use - python -m unittest discover -v from the root package directory.
For an overview of neuroptica, read the documentation. Example notebooks are included in the neuroptica-notebooks repository:
