Abstract
We report on the fabrication and characterization of a monolithically integrated balanced mixer receiver on InP consisting of a 3-dB coupler, twin balanced waveguide integrated photodiodes, and a low-noise electrical preamplifier. The receiver OEIC exhibits a transimpedance of 223 Omega and a 3-dB bandwidth of 1 GHz. Heterodyne operation and local laser noise cancellation capability of the OEIC are demonstrated.Keywords
