Abstract:
To provide a multiplexer that makes it possible to achieve a reduction in size and that minimizes the influence of the expansion of laser light on a multiplexing unit. A multiplexer is provided with a plurality of waveguides, multiplexing units that are provided at an intermediate location within the waveguides, and laser light sources, wherein: the first multiplexing unit is arranged at a position that is closest to the laser light sources; and the laser light sources that have an optical axis at a position that is separated from the transmission axis of the visible light that is introduced into the first multiplexing unit are arranged so that the optical axis is inclined with respect to the transmission axis and the outer periphery of laser light that expands at a predetermined expansion angle passes in front of the first multiplexing unit.

Claim (Index 1):
A multiplexer that can wavelength multiplex a plurality of visible light rays having different wavelengths, comprising: a plurality of waveguides into which the visible light rays enter; a plurality of multiplexing units that are provided in the middle of a waveguide and can mode couple the visible light rays that propagate through at least two waveguides; and a plurality of laser beam sources for irradiating each waveguides with the visible light rays, wherein\n the multiplexing unit placed the closest to the plurality of laser beam sources is a first multiplexing unit, and all of the laser beam sources of which the optical axes are located at a distance away from the axis along which the visible light ray that is led into the first multiplexing unit propagates are arranged in such a manner that the optical axes are inclined relative to the axis along which the visible light ray that is led into the first multiplexing unit propagates so that the laser beams that spread at a predetermined spread angle pass in front of the first multiplexing unit without irradiating the laser beams including the outer periphery of the laser beams for the first multiplexing unit to suppress the influence on the multiplexing units of the spreading of the laser beams from the laser beam sources so that stray light is not generated.
