Abstract

An optical 90°hybrid is used for demodulating the information encoded in the phase and amplitude of an incoming optical signal by interfering it either with a local oscillator or with itself. Such 90° hybrids are essential for retrieving the amplitude of both orthogonal quadratures of the received signal in applications such as coherent communications, or continuous-variable quantum key distribution. In this work, we report on the design and the results from a monolithically integrated optical 90° hybrid, based on a 4×4 multi-mode interference coupler fabricated in the generic InP platform of Smart Photonics. We investigated the performance of the hybrid in terms of its common-mode rejection ratio, and phase mismatch across the full C-band.
