Abstract

Official abstract text for this publication.

An optical circuit, wherein the effects of reflected light generated by an optical component are reduced. The optical circuit ( 100 ) is provided with an optical branching ( 110 ) for branching light, an optical coupler ( 114 ) for coupling a first portion of branched light to an optical waveguide ( 118 ) for transmission, and an optical reflecting unit ( 116 ) for reflecting a second portion of the branched light, the phase difference between the reflected light from the optical coupler ( 114 ) and the reflected light from the optical reflecting unit ( 116 ) being (2m−1)π (where m is an integer) on an input side of the optical branching ( 110 ).

First claim

Opening claim text (preview).

The invention claimed is: 1. An optical circuit comprising: a first branching part configured to branch light; a first optical coupler configured to couple first branched light in the branched light to a first optical waveguide for transmission; and an optical reflection part configured to reflect second branched light in the branched light; wherein, at an input side of the first branching part, a phase difference between reflected light from the first optical coupler and re…
