Document Type and Number:
WIPO Patent Application WO/2021/177166
Kind Code:
A1
Abstract:
Provided is an optical multiplexing device that facilitates the placement of a laser diode which is a light source, and the like, reduces electrical crosstalk and light loss, and is integrally miniaturized. Output directions of light sources (2, 3, 4) for a plurality of beams having mutually different wavelengths are inclined in a left-right direction at an angle of ±5º-80º with respect to an output light direction (M1) of the optical multiplexing device (1), whereby the miniaturization of the optical multiplexing device is achieved.
