Abstract:
1. A method of manufacturing an optical waveguide device, comprising: obtaining an optical waveguide by forming sequentially a first cladding layer, a core layer, and a second cladding layer on a substrate; forming a groove portion including a light path conversion inclined surface and a sidewall surface which intersects with the light path conversion inclined surface, and the groove portion dividing the second cladding layer and the core layer, on both end sides of the optical waveguide respectively; forming selectively a metal layer on the light path conversion inclined surface and the sidewall surface of the groove portion; forming a protection insulating layer sealing the metal layer on the optical waveguide; and obtaining a light path conversion mirror that the metal layer is formed on the light path conversion inclined surface, by forming a concave portion which penetrates the core layer from the protection insulating layer to remove the metal layer formed on the sidewall surface of the groove portion, wherein the light path conversion mirror is covered with the protection insulating layer, and a processed surface of the light path conversion mirror is exposed in a sidewall of the concave portion.
