Abstract
The invention provides an optical fiber array assembly. The optical fiber array assembly comprises a three-dimensional optical waveguide chip, a single-mode optical fiber array and a multi-mode optical fiber array, wherein an input end waveguide of the three-dimensional optical waveguide chip is connected with the multi-mode optical fiber array, and an output end waveguide of the three-dimensionaloptical waveguide chip is connected with the single-mode optical fiber array. The optical fiber array assembly is advantaged in that the three-dimensional optical waveguide chip is arranged between the multimode optical fiber array and the single-mode optical fiber array, the three-dimensional optical waveguide chip is used for replacing a bent optical fiber between the multimode optical fiber array and the single-mode optical fiber array, the three-dimensional optical waveguide in the three-dimensional optical waveguide chip is used for turning optical signals, the production and manufacturing process of the optical fiber array is simplified, and the situation that reliability of a product is reduced due to the fact that the optical fiber is in a high-bending state by directly bending the optical fiber is avoided.
Description
technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to an optical fiber array assembly. Background technique [0002] With the development of optical communication network technology and optical computing, silicon electronic integration technology has received more and more attention. Various optical and electronic devices are integrated on silicon electronic chips, and optical fiber arrays need to be used for optical coupling with the optical devices on the chip. Due to space constraints, ultra-small 90° steering fiber arrays are often used. [0003] At present, the 90°-steering optical fiber array basically bends the optical fiber directly in a very small space. The manufacturing process is difficult, and the optical fiber is always in a state of high bending stress, which affects the long-term reliability of the product. SUMMARY OF THE INVENTION [0004] In view of this, the purpose of the present invention ...
