Abstract

A compact photonic radio frequency front end receiver system including a laser chip source, radio frequency and LO inputs, an optical modulator chip coupled to the laser source and the radio frequency and LO inputs, a millimeter scale optical radio frequency multi-pole filter coupled to the optical modulator, an optical switch array chip coupled to the optical radio frequency multi-pole filter, and a detector chip coupled to the optical switch array, all with micro-optic coupling, heterodyne signal recovery, and wavelength locking.
