OPTICAL TRANSMISSION LINE, OPTICAL TRANSMISSION SUBSTRATE, AND OPTICAL MODULE

摘要

PROBLEM TO BE SOLVED: To provide an optical transmission line that reduces optical transmission loss.

SOLUTION: The optical transmission line includes: a core that has an optical path conversion surface for converting the travelling direction of light; a clad that covers the periphery of the core and that has a refractive index lower than that of the core; and a resin layer installed on the clad so that the surface of the clad including the optical path conversion surface is exposed as the bottom face of a recess in a transmission plane view.
