Multichannel integrated optical wavelength division multiplexing/demultiplexing component structure

Abstract

The invention provides a multichannel integrated optical wavelength division multiplexing / demultiplexing assembly structure. The multichannel integrated optical wavelength division multiplexing / demultiplexing assembly structure comprises a light emission assembly and a light receiving assembly, the light emission assembly comprises a laser chip array, a coupling lens assembly, a wavelength division multiplexing assembly, a coupling single lens and a single-core optical fiber. The wavelength division multiplexing assembly comprises a light waveguide chip, a bandpass filter set, a broad spectrum reflector element and multiple Z-shaped or W-shaped waveguide light paths which are continuously distributed in the light waveguide chip. The multiple waveguide light paths are respectively provided with an input port and an output port which are distributed on the left side face and the right side face of the light waveguide chip respectively, and the output ports are provided with tail end ports and are arranged corresponding to the coupling single lens. The bandpass filter set covers the input ports, and the broad spectrum reflector element covers the output ports except the tail end ports. By means of the combination consisted of the above structure, the technical problem that the overall light path precision is poor is solved, and the advantages of being easy to assemble, lowering cost and improving product yield are achieved.

Description

technical field [0001] The present invention relates to the technical field of optical communication, in particular to a multi-channel integrated optical wavelength division multiplexing / demultiplexing component structure. Background technique [0002] With the rapid growth of bandwidth requirements of modern communications, the requirements of optical communication systems for high-speed optical transceiver modules and optical transmitting and receiving components inside the modules are continuously increasing. The main development trend is that the speed is getting higher and higher. It is also getting smaller and smaller, and the power consumption is getting lower and lower. [0003] At present, the rate of semiconductor lasers is limited by the bottleneck of semiconductor optoelectronic technology, and the rate of single-channel commercial products cannot be increased for the time being. In order to improve the transmission capacity per unit volume of optical communicat...
