Abstract
Systems and methods of monitoring optical transmitter signals are described. In one aspect, an optical transmitter system includes a feedback block, an optical substrate, a source of input light within an operative wavelength range, and a detector. The feedback block is substantially transparent to light within the operative wavelength range and includes an optical fiber side having a light output and one or more reflectors, and an optical substrate side. The optical substrate is substantially transparent to light within the operative wavelength range. The optical substrate includes a device side having a light input, and a feedback block side that is coupled to the optical substrate side of the feedback block. The feedback block side has a splitter that is operable to split light that is received from the device side light input into an output beam that is directed toward the light output of the feedback block and a light sample that is directed toward a feedback block reflector. The source of input light is mounted to the device side of the optical substrate and is aligned for light transmission through the device side light input to the splitter. The detector is mounted to the d…
