Publication number: 20200132274Abstract: A wavelength division multiplexing module adapted to combine a plurality of light beams to a mixed light beam is provided. The wavelength division multiplexing module includes a housing, a plurality of light emitting elements, an optical division element, and a plurality of reflectors. The light emitting elements are adapted to provide light beams. The optical division element is disposed on a transmission path of the light beams. The reflectors are disposed on the transmission path of the light beams. The optical division element has a reflection region and a light transmission region on one side opposite to the light emitting elements. The reflection region is adapted to reflect a portion of the light beams, and the light transmission region is adapted to allow the mixed light beam to pass through. At least two of the light emitting elements are arranged in an extending direction of the housing.Type: ApplicationFiled: March 11, 2019Publication date: April 30, 2020Applicant: ELITE ADVANCED LASER CORPORATIONInventors: Chu-Liang Cheng, Chi-Hua Wang
