Neuromorphic photonics with coherent linear optical neurons
Summary
The USPTO published patent application US20260093974A1 by Pleros et al. covering neuromorphic photonic computing systems using coherent linear optical neurons implemented with multipath optical interferometers. The application includes optical amplitude modulators, phase shifters, and photodetectors for non-linear activation functions in optical neural networks. The patent was filed on July 7, 2025, under application number 19261861.
What changed
The USPTO published a patent application for neuromorphic photonics technology featuring coherent linear optical neurons. The invention uses multipath optical interferometers where optical amplitude modulators and phase shifters imprint neuron input signals and weights onto optical carriers, which are then summed at the interferometer output. Photodetectors at the output optionally work with nonlinear optical circuits to implement activation functions, generating electronic outputs for subsequent optical neurons.
This is a patent application publication only and creates no compliance obligations. Technology companies, semiconductor manufacturers, and AI/optical computing researchers may review the claims for prior art purposes or to assess freedom-to-operate for optical neural network development. No deadlines, penalties, or required actions apply to this document.

Abstract
Neuromorphic computing can employ coherent linear optical neurons implemented with multipath optical interferometers in which optical amplitude modulators and phase shifters impart neuron input signals and neuron weights onto optical carrier signals that are then summed at the interferometer output. Photodetectors at the interferometer output, optionally in conjunction with preceding nonlinear optical circuits, may implement a non-linear activation function and generate electronic neuron output signals that can be provided as input to other optical neurons to form an optical neural network.
