Abstract:
1. Apparatus comprising: first and second ridge type photonic waveguides, each of the first and second waveguides including a core layer having a core index of refraction, the core aver being formed to have both a ridge of a dimension and shape to impose lateral confinement and a laterally extending slab extension, and each of the first and second waveguides further including a reflective cladding layer in continuous contact with a first side of the core layer, the reflective cladding layer having an index of refraction substantially different than the core index of refraction; an inter-waveguide slab portion between the first and second waveguides; a substrate supporting the first and second waveguides, the slab portion, and the reflective cladding layer; and a light interceptor region to hinder a transfer of photons between the first and second waveguides through the inter-waveguide slab portion.
