Abstract
The invention is a semiconductor device, and a method of fabrication, where a waveguide layer in which light is propagated and an integral photodetector are formed in the device. A light absorbing layer of the photodetector includes a portion of the waveguide layer which is modified to absorb a portion of the light while transmitting the remainder of the light. Additional components, such as a laser, optical amplifier and modulator can be included with the photodetector.
