ABSTRACT:
A quartz optical waveguide comprising a substrate, a ridge-form core part formed on said substrate and a part which surrounds said core part and has a lower refractive index than that of said core part, wherein a refractive index changes continuously at an interface between said core part and said part having the lower refractive index, which has a decreased transmission loss and a connection loss when connected with an optical fiber.
