We present an electronic technique to control photonic processors based on Mach–Zehnder interferometers. By leveraging transparent photodetectors and local feedback loops, the working point of each interferometer is automatically configured. The concurrency of two control loops per device enables the computation of 2 × 2 vector–matrix multiplications in the analog domain, enabling scalable optical computing.

Abstract
We present an electronic technique to control photonic processors based on Mach–Zehnder interferometers. By leveraging transparent photodetectors and local feedback loops, the working point of each interferometer is automatically configured. The concurrency of two control loops per device enables the computation of 2 × 2 vector–matrix multiplications in the analog domain, enabling scalable optical computing.File in questo prodotto:
