Patent ID: 6892007

Claim:
An optical transmitter system, comprising: a feedback block substantially transparent to light within an operative wavelength range and including an optical fiber side having a light output and one or more reflectors, and an optical substrate side; an optical substrate substantially transparent to light within the operative wavelength range, the optical substrate including a device side having a light input, and a feedback block side coupled to the optical substrate side of the feedback block and having a splitter operable to split light received from the device side light input into an output beam directed toward the light output of the feedback block and a light sample directed toward a feedback block reflector; a source of input light within the operative wavelength range mounted to the device side of the optical substrate and aligned for light transmission through the device side light input to the splitter; and a detector mounted to the device side of the optical substrate and aligned for detection of the light sample transmitted from a feedback block reflector and through the feedback block and the optical substrate.
