Optical waveguide and optical module

摘要

An optical waveguide includes a first cladding layer, at least two core portions formed on the first cladding layer and extended in a first direction, at least two groove portions formed in each of the core portions at positions spaced apart from each other in the first direction, each groove portion having an inclined surface, an optical path conversion mirror formed on one of the inclined surfaces formed in each of the core portions, and a second cladding layer formed on the first cladding layer and the core portions. The optical path conversion mirrors formed in the core portions adjacent to each other are arranged at positions different from each other in the first direction. The groove portions formed in the core portions adjacent to each other are arranged at the same positions in the first direction.
