OPTICAL CIRCUIT |
| 摘要 |
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). |

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 reflected light from the optical reflection part is (2m−1)π, wherein m is an integer. |
