Wavelength division multiplexing optical assembly based on arrayed waveguide grating technology

Abstract

The invention provides a wavelength division multiplexing optical assembly based on an arrayed waveguide grating technology. The wavelength division multiplexing optical assembly comprises a laser collimation sub-component, an arrayed waveguide grating sub-component and an output optical fiber, wherein the laser collimation sub-component is formed by solidifying a laser chip and a laser collimation lens array, and the arrayed waveguide grating sub-component is formed by solidifying an arrayed waveguide grating collimation lens array, an arrayed waveguide grating and an arrayed waveguide grating coupling optical fiber lens array. Two discrete modules in a traditional wavelength division multiplexing optical assembly are integrated, so that the development requirement of further miniaturization of the modules is met, materials can be simplified, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a wavelength division multiplexing optical component based on arrayed waveguide grating technology. Background technique [0002] With the development of 5G and data centers, communication systems have increasingly higher requirements for optical communication transmission rates, and more stringent requirements have been placed on optical module size and cost. Therefore, the demand for parallel transmission optical modules is increasing rapidly, especially the parallel transmission optical modules based on wavelength division multiplexing technology, which has attracted special attention due to its large bandwidth capacity and long transmission distance. [0003] The existing optical path form of wavelength division multiplexing optical components based on arrayed waveguide grating technology generally adopts the coupling of arrayed waveguide grating and fiber array...
