Abstract
A simple configuration for achieving a radio frequency transparent 90° hybrid, for broadband QAM wireless systems using silicon photonics is proposed. The device consists of a high Q ring resonator which induces an optical 90° phase shift between two adjacent resonant wavelengths. When these optical carriers are modulated by an RF carrier the resulting device behaves as an RF 90° hybrid. Numerical simulations of the phase shift were performed on a 40 GHz carrier, and to demonstrate the frequency transparency phase shift simulations was also performed at a carrier frequency of 60 GHz. One of the main applications of such a device is the generation of millimeter wave 10 Gb/s wireless based on quadrature amplitude modulation.
