Original Abstract Submitted
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.
