発明の名称 (英語) MULTIPLEXER, IMAGE PROJECTION DEVICE USING SAME, AND IMAGE PROJECTION SYSTEM コモンズ
発明の概要(英語) [Problem] To provide a multiplexer that makes it possible to achieve a reduction in size and that minimizes the effect of the expansion of laser light from a laser light source on a multiplexing unit. [Solution] A multiplexer that performs wavelength multiplexing of a plurality of types of visible light that have differing wavelengths, that is provided with a plurality of waveguides (101, 102, 103) into which the plurality of types of visible light enter, multiplexing units (110, 120, 130) that are provided at an intermediate location within the waveguides and that perform mode coupling of visible light that is transmitted by at least two of the waveguides, and laser light sources (16a, 16b, 16c) that irradiate the waveguides with the visible light, and wherein: the first multiplexing unit (110) is arranged at a position that is closest to the laser light sources; and the laser light sources (16a, 16c) that have an optical axis (X) at a position that is separated from the transmission axis (Y) of the visible light that is introduced into the first multiplexing unit (110) are arranged so that the optical axis is inclined with respect to the transmission axis and the outer edge of laser light that expands at a predetermined expansion angle passes in front of the first multiplexing unit.
