Abstract
A mode field size converting optical channel waveguide with tapered refractive index and cross-sectional dimensions is proposed. The layer thicknesses and the core index of a silica waveguide were tapered along the waveguide by modulating the raw material gas flow in a flame hydrolysis deposition method. A channel width taper was also formed by photolithography.
