OPTICAL WAVEGUIDE, OPTICAL WAVEGUIDE MANUFACTURING METHOD, AND OPTICAL MODULE

摘要

An optical waveguide is provided with a substrate 1, a lower cladding layer 2 that is formed on the substrate 1, an optical signal transmitting core pattern 31 and a protruding pattern 32 that are disposed on the lower cladding layer 2, and an upper cladding layer 4 that is disposed in a manner that it covers the optical signal transmitting core pattern 31 in association with the lower cladding layer 2. The protruding pattern 32 has an outer peripheral wall 33 that protrudes out of the substrate 1, the lower cladding layer 2, and the upper cladding layer 4 in an outer peripheral direction of the substrate 1.
