MULTI-MODE INTERFEROMETRIC OPTICAL WAVEGUIDE DEVICE AND PHOTONIC INTEGRATED CIRCUIT

摘要

A multi-mode interferometric optical waveguide device (1) comprises: a multi-mode interferometric waveguide (10) including a first reflective surface (15); a first single mode waveguide (20) connected to the multi-mode interferometric waveguide (10); and a second single mode waveguide (21) that is connected to the multi-mode interferometric waveguide (10) and faces the first reflective surface (15). This configuration allows the multi-mode interferometric optical waveguide device (1) to transfer light from the first single mode waveguide (20) to the second single mode waveguide (21) with even less light loss.
