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.
