摘要
A multi-mode interference multiplexer/demultiplexer can suppress reflected return light while guiding light to a single-mode waveguide. The multi-mode interference multiplexer/demultiplexer includes a multi-mode waveguide, a first single-mode waveguide connected to a first end, a second single-mode waveguide opposing the first single-mode waveguide, a third single-mode waveguide connected to a second end, a reflecting surface opposing the third single-mode waveguide, and a fourth single-mode waveguide connected to a side end. Light entering from the second or third single-mode waveguide is reflected off the reflecting surface and forms an image at a first connection on a side end of the fourth single-mode waveguide.
