Patent ID: 10727948

Abstract:
Optical transmitters, receivers, and transceivers implemented using a plurality of surface-coupled optical devices that can be manufactured on the same planar substrate and then post-processed to provide some of the devices with different respective partially transparent front mirrors compatible with and/or customized for different respective optical functions. When appropriately electrically biased and driven, different subsets of such devices can operate as lasers, optical modulators, optical amplifiers, and photodetectors, respectively. In this manner, an integrated array of such devices can be customized to provide the optical functions needed for the intended product. For example, an optical transmitter can be constructed using an integrated array that comprises three surface-coupled optical devices configured to operate as a laser, an optical modulator, and an optical amplifier, respectively. An optical receiver can be constructed using an integrated array that comprises two surface-coupled optical devices configured to operate as an optical amplifier and a photodetector, respectively.
