A multi-channel integrated optical wavelength division multiplexing/demultiplexing assembly structure, comprising a light transmitting assembly (10) and a light receiving assembly (20); the light transmitting assembly (10) comprises a laser chip array (11), a coupling lens set (12), a wavelength division multiplexing assembly (13), a coupling simple lens (14) and a single-core optical fiber (15); the wavelength division multiplexing assembly (13) comprises an optical waveguide chip (131), a band pass optical filter set (132), a full wavelength reflection unit (133), and multiple segments of waveguide optical paths (134) continuously arranged in the optical waveguide chip (131) in a Z shape or a W shape; the multiple segments of waveguide optical paths (134) all have input ports (I1 … In) and output ports (O1 … On), and are respectively distributed on the left and right sides of the optical waveguide chip (131); the output ports (O1 … On) have end ports, and are disposed corresponding to the coupling simple lens (14); the band pass optical filter set (132) covers the input ports (I1 … In); and the full wavelength reflection unit (133) covers the output ports other than the end ports, thus solving the technical problem of deviations in precision of the entire optical path, and achieving the effects of easy assembly, reduced costs and increased product yield. |
