Abstract: Embodiments are directed to photonic integrated circuits that include a carrier-based phase shifter. The carrier-based phase shifter is configured as a PIN phase shifter with a pair of traces that delivers current through a PIN diode. The PIN phase shifter is configured such that current flows through the pair of traces in a common direction.

Abstract: Embodiments are directed to photonic integrated circuits that include a carrier-based phase shifter. The carrier-based phase shifter is configured as a PIN phase shifter with a waveguide formed from a strip extending from a slab waveguide. The PIN phase shifter includes a first set of doping regions positioned in a slab waveguide and a second set of doping regions positioned the strip. Each of the first set of doping regions has a first conductivity type, and each of the second set of doping regions has a second conductivity type that is different that the first conductivity type.

Abstract: Various embodiments disclosed herein describe photonic switch. The controllable photonic switch may be configured with an asymmetry and different doping level that concurrently route two different wavelengths of light by wavelength-dependent phase shifters. In some instances, the controllable photonic switch includes a waveguide having an asymmetric cross-sectional shape. In other instances, the controllable photonic switch selectively route different wavelengths of light to different outputs of the controllable photonic switch.
