Abstract

See full text

An optical circuit includes a wiring board and an optical waveguide. Part of an upper surface of the wiring board is a mounting region of an optical component. The optical waveguide is positioned adjacent to the mounting region of the optical component on the wiring board, and includes a core, a first cladding, and a second cladding. The core includes a first portion and a second portion. The first cladding is positioned sandwiching upper and lower surfaces of the first portion of the core, and the second cladding is positioned sandwiching upper and lower surfaces of the second portion of the core. The width of the second portion is greater than the width of the first portion, and the thickness of the second portion is greater than the thickness of the first portion. The refractive index of the second cladding is greater than the refractive index of the first cladding.
