OPTICAL WAVEGUIDE AND OPTICAL WAVEGUIDE MODULE

摘要

Provided is an optical waveguide module that is not only capable of ensuring a high-precision, stable optical connection between an optical element and an optical waveguide but that can also be manufactured easily. As a means to this end, with an optical waveguide module equipped with an optical waveguide that is enclosed with a clad layer and has a mirror section made with a tapered surface at one end, an optical element that has a concave section on a first surface of a semiconductor substrate, and a convex member that is provided on the aforementioned clad layer to overlap planarly with the aforementioned mirror section, the aforementioned convex member is fitted into the aforementioned concave section of the optical element.
