Abstract
A method and system for integrated power combiners are disclosed and may include a chip comprising a polarization controller, the polarization controller comprising an input optical waveguide, optical couplers, and a polarization-splitting grating coupler. The chip may be operable to: generate two output signals from a first optical coupler that receives an input signal from said input optical waveguide, phase modulate one or both of the two output signals to configure a phase offset between the two generated output signals before communicating signals with the phase offset to a second optical coupler. One or both optical signals generated by said second optical coupler may be phase modulated to configure a phase offset between signals communicated to the polarization-splitting grating coupler; and an optical signal of a desired polarization may be launched into an optical fiber via the polarization-splitting grating coupler by combining the signals communicated to the polarization-splitting grating coupler.
