Document Type and Number:
WIPO Patent Application WO/2020/162216
Kind Code:
A1
Abstract:
The present invention improves crosstalk between ports while maintaining compactness of an interposer circuit. This interposer circuit is provided with: a first surface that is a connection surface with an optical circuit (201); a second surface that is a connection surface with a fiber block (203) and faces the first connection surface in parallel; and a plurality of connection waveguides (205) connected with a plurality of input/output waveguides (204) the optical circuit has and a plurality of input/output fibers (206) the fiber block has, wherein the plurality of connection waveguides are linearly shaped, and an angle (θ) formed by the plurality of connection waveguides (205) and the first surface and an angle (φ) formed by the plurality of connection waveguides (205) and the second surface are the same.
