摘要
A light source unit includes an optical coupler, light sources, a light output portion, a light sensor, and a controller. The optical coupler is formed by joining intermediate portions of plural optical fibers together and multiplexes lights, which have entered respective one ends of the optical fibers, in a coupling region where the intermediate portions of the optical fibers are joined together. The light sources emit light of different wavelengths that enter the respective one ends of the plural optical fibers. The light output portion is formed by the other end of one of the plural optical fibers and outputs the multiplexed lights. The light sensor detects light emerging from the other end of at least another one of the plural optical fibers.
