Claim 18:
19. An integrated optical circuit, comprising:
a first substrate formed of a first material;
a first waveguide formed of a second material and positioned on the first substrate, wherein the first waveguide is configured to split and polarize light beams that propagate through the first waveguide;
a second substrate formed of a third material, wherein the second substrate is coupled to or positioned on the first substrate;
a plurality of phase modulators positioned on or in the second substrate, wherein each respective phase modulator of the plurality of phase modulators is optically coupled to a respective branch of the first waveguide, wherein each respective phase modulator of the plurality of phase modulators is configured to modulate a phase of light beams that propagate through the respective phase modulator; and
a plurality of straight waveguides formed of the second material and positioned on the first substrate or a third substrate, wherein each respective straight waveguide of the plurality of straight waveguides is optically coupled to a respective phase modulator of the plurality of phase modulators positioned between the first waveguide and the respective straight waveguide of the plurality of straight waveguides, wherein each respective straight waveguide of the plurality of straight waveguides is configured to polarize light beams that propagate through the respective straight waveguide of the plurality of straight waveguides.
