Abstract: An integrated circuit comprises: at least one photonic layer that includes one or more optical waveguides; a first optical coupler that couples at least a first optical mode outside of the photonic layer to a first waveguide in the photonic layer; a photonic device that includes one or more ports in the photonic layer; a first multi-port optical coupler that includes three or more ports in the photonic layer, including a first port optically coupled to the first optical coupler, a second port optically coupled to a first port of the photonic device, and a third port optically coupled to a first optical reflector configured to send substantially all optical power emitted from the third port of the first multi-port optical coupler back to the third port of the first multi-port optical coupler.

Abstract: A phase modulator with reduced Residual Amplitude Modulation includes a main path; a correction path; a first coupler configured to split, at a first ratio, an input to the main path and the correction path; and a second coupler configured to combine outputs from the main path and the correction path and to split the combined outputs, at a second ratio, with a first output comprising an output of the phase modulator with the reduced Residual Amplitude Modulation. The correction path can include a correction signal with a proper amplitude and phase that, when combined with an output signal from the main path by the second coupler, cancels the Residual Amplitude Modulation from the output signal.

Abstract: An optical modulator includes a rib; and a slab interconnected to both sides of the rib; wherein the rib is dimensioned relative to the slab to support guiding of a Transverse Magnetic (TM) mode with a main lobe that propagates orthogonal to the slab and with the main lobe substantially excluded from the slab. The rib guides wavelengths in an infrared range in the TM mode. A height of the rib, relative to the slab, is about half of a width of the rib, between the slab.

Abstract: A silicon photonics modulator includes a rib that is a PN junction; a slab including a P doped region adjacent to the waveguide core on a first side and an N doped region adjacent to the waveguide core on a second side, opposite the first side; and a first electrode connected to the P-doped region and a second electrode connected to the N-doped region, wherein the rib is dimensioned to support guiding of a Transverse Magnetic (TM) mode with a main lobe that propagates orthogonal to the slab. The rib guides wavelengths in an infrared range in the TM mode.
