Abstract:
1. An optical power combining system comprising: an optical splitter receiving an optical signal and providing a plurality of splitter outputs; a plurality of optical channels, at least one optical channel of said plurality of optical channels comprising an amplifier coupled to a waveguide, each optical channel being coupled to a corresponding splitter output and each channel producing a corresponding channel output; an optical combining network comprising one or more waveguide couplers, said optical combining network coupled to one or more of the channel outputs of the plurality of optical channels, said optical combining network coherently combining, in said one or more waveguide couplers, the channel outputs into one or more combined outputs; and a feedback loop having a feedback input and one or more feedback outputs, said feedback input being coupled to at least one of said one or more combined outputs, and said one or more feedback outputs being coupled to one or more of said amplifiers; wherein at least one amplifier has a laser pump and a current driving said laser pump is adjusted, thereby introducing a dithered frequency in an associated optical channel.
