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.

Wavelength division multiplexing module

An optical module adapted to combine a first and a second light beam into a mixed light beam is provided. The optical module includes a base, an optoelectronic element and an optical dichroic element. The base has an accommodating space. The optoelectronic element is adapted in the accommodating space. The optical dichroic element is adapted on the base. The optical dichroic element includes a transparent element, a first reflector and a second reflector. The transparent element is adapted to let the first light beam and the second light beam pass through. The first and second reflector are disposed on the transparent element. The first reflector is adapted to reflect the first light beam to the second reflector. The second reflector is adapted to reflect the first light beam and let the second light beam pass through. The first and the second reflector are opposite and not parallel to each other on the transparent element, and there is an angle between the first and the second reflector.

Optical module

A beam-splitting integrated optical element including a shell, at least one first lens, and at least one second lens is provided. The shell includes a first lens surface, a second lens surface, at least one first reflective surface, and at least one second reflective surface. A bottom edge of each first reflective surface and a bottom edge of each second reflective surface are not connected to each other. The at least one first lens is disposed on the first lens surface. The at least one second lens is disposed on the second lens surface, and each second lens has a second optical axis. Each second reflective surface is located at at least one side of the corresponding second optical axis and located on a transmission path of only a portion of a first beam. An optical transmitter module incorporating said beam-splitting optical element is also provided.
