Robust free space optical communication receiver based on a spatial mode demultiplexer and a silicon photonic coherent combining circuit

Abstract

Mitigation of atmospheric perturbations is a major challenge in optical wireless communications. We propose and prove the concept of a robust free space optical communication receiver based on an optical spatial mode demultiplexer and a silicon photonic coherent combining circuit. The receiver collects the light from several spatial modes with a multiplane light converter and coherently combine the energy from the different modes with an on chip, self-configuring, interferometer binary tree circuit. This solution offers a higher collection efficiency than standard free space optical receiver and shows a strong robustness to phase and intensity perturbation.
