Title:
WAVELENGTH DIVISION MULTIPLEXING OPTICAL COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/232779
Kind Code:
A1
Abstract:
A wavelength division multiplexing optical communication device, comprising a diffractive optical assembly (1), an adjusting assembly, a receiving port (2), a plurality of optical lenses (3), and a plurality of filters (4) having different wavelengths. A plurality of mounting holes (5) are provided in the diffractive optical assembly (1) at intervals; the optical lenses (3) are arranged in the mounting holes (5); the adjusting assembly is located in the diffractive optical assembly (1) and rotatably connected to the diffractive optical assembly (1); the plurality of filters (4) are obliquely disposed on the adjusting assembly; each filter (4) is disposed corresponding to the position of the optical lens (3) so as to shield light incident from the optical lens (3); the receiving port (2) is disposed in one end of the diffractive optical assembly (1) and located on a light exit path of the diffractive optical assembly (1); light incident from the plurality of optical lenses (3) is reflected by the plurality of filters (4) respectively and then converged to the receiving port (2); and the adjusting assembly is used for driving the plurality of filters (4) to synchronously rotate, relative to the diffractive optical assembly (1), by an angle within a preset range, thereby achieving the adjustment of output optical power.
