1. A method for operating an electro-optic combiner, comprising:
receiving incoming light through an optical input port of a photonic circuit, wherein a first portion of the incoming light has a first polarization and a second portion of the incoming light has a second polarization;
splitting the first portion of the incoming light from the second portion of the incoming light;
directing the first portion of the incoming light through a first optical waveguide;
rotating the second polarization of the second portion of the incoming light to the first polarization so that the second portion of the incoming light is a polarization-rotated second portion of the incoming light;
directing the polarization-rotated second portion of the incoming light through a second optical waveguide; and
operating a plurality of ring resonators disposed between the first optical waveguide and the second optical waveguide, wherein each of the plurality of ring resonators is operated to evanescently in-couple light from the first optical waveguide and out-couple light into the second optical waveguide.
