DIELECTRIC WAVEGUIDE INTERSECTION WITH REDUCED LOSSES

摘要

A waveguide intersection (300) includes an input waveguide (205) and an output waveguide (210); a crossing waveguide (215) intersecting the input waveguide (205) and the output waveguide (210) to form an intersection (135); and a block (305, 310) that is optically joined to the intersection (135) such that a guided mode (405) is produced within the intersection (135). A method of reducing optical losses within a waveguide intersection (300) includes increasing a cross-sectional height of an intersection (135) such that optical energy (405) passing through the intersection (135) is laterally confined.
