NeuroPhotonics

The main goal of the NeuroPhotonics project is to realize a highly-scalable, physics-informed design platform for on-chip optical systems with arbitrary functionality, based on a deep photonic network of custom-designed Mach-Zehnder interferometers.

NeuroPhotonics is funded by the Marie SklodowskaCurie Fellowship (no 101032147) through the Horizon 2020 program of the European Commission.

Structure and Capabilities

The main project findings are published in our article “Deep Photonic Network Platform Enabling Arbitrary and Broadband Optical Functionality”, available currently as a preprint. Below are some highlights from this preprint.

The main building block of the network is a Mach-Zehnder interferometer constructed from couplers and custom waveguides. These interferometers are then horizontally and vertically cascaded to create the network.

The photonic network is trained and optimized using a target optical functionality, through an iterative procedure using the derivative of the final device response with respect to the design parameters.
