Abstract:
An optical waveguide coupler is provided that includes an InP substrate, a guiding core layer disposed on the InP substrate, a top cladding layer disposed on the guiding core layer, where the guiding core layer and the top cladding layer are disposed in a photosensitive housing waveguide, and a mode coupling region having a lateral taper of the guiding core layer and the top cladding layer disposed above a region where the InP substrate is at least partially removed to create an air-cladding, where a low-to-high refractive index contrast transition (RICT) InP-based waveguide device is established to minimize light leakage into the InP substrate.

Claim (Index 5):
The optical waveguide coupler of  claim 1 , wherein said guiding core layer comprises InGaAsP.
