1. A system for modulating polarization of an optical beam, the system comprising:
a light source for generating light into a first waveguide and a second waveguide;
a first grating coupler for coupling the light from the first waveguide into an output emission;
a second grating coupler for coupling the light from the second waveguide into the output emission; and
at least one phase shifter for shifting the phase of the light between the first waveguide and the second waveguide in order to control a polarization of the output emission.
