Patent ID: 7780360

Claim:
A system comprising: an optical system having a processor coupled with a storage medium, the optical system further having waveguides formed in a semiconductor substrate to propagate an optical signal received at a first end of the waveguides; a trench formed in the waveguides having a first sidewall and a second sidewall, the first and second sidewalls forming first and second angles with the optical signals propagation direction; a reflective surface formed on the second sidewall; and a detector array to receive respective an optical signal propagated in the waveguides, through the first sidewall and reflected from the reflective surface on the second sidewall, wherein the detector array coupled to the waveguides and a plurality of laser gain blocks, the detector array to provide wavelength stabilization for the waveguides, to provide power usage equalization of the plurality of laser gain blocks, to monitor power of optical signals, and to balance the power of the optical signals by increasing and/or decreasing each optical signal to achieve a desired power level.
