Abstract
In order to make it possible to suppress the influence of reflected light on a connection interface easily and with certainty, an optical waveguide device includes a first optical waveguide (1), a second optical waveguide (2) formed from a material or in a structure different from that of the first optical waveguide (1) and connected to the first optical waveguide (1), and a 1×1 multimode interference waveguide (3) formed by increasing the widths of the first optical waveguide (1) and the second optical waveguide (2) in the proximity of a connection interface between the first optical waveguide (1) and the second optical waveguide (2).
