Fiber Array ( FA) is an array formed by using a V-groove (V-groove, V-Groove) substrate to install a bundle of optical fibers or a fiber ribbon on the substrate at a specified interval. The processing process of the optical fiber array is that the bare optical fiber part from which the optical fiber coating is removed is placed in the V-shaped groove, pressed by the presser component, and bonded by the adhesive, and finally the surface is polished and polished to the desired position.
Need precision. At the front end, the optical fiber is precisely positioned to connect to the PLC. The splices of different optical fibers are mounted on the substrate.
The optical fiber array is mainly used to transmit information in optical communication, and it can also transmit images directly.
Many optical fibers are arranged in a certain order into the required geometric shapes to form an optical fiber array. The positions of the optical fibers at both ends of the array correspond to each other.
One optical fiber in the array is equivalent to a pixel, and the optical image at one end of the optical fiber array will be in the array. Reappear on the other end. Various optical fiber endoscopes in medicine are made on this principle.
With the development of the communication field, the demand for high-speed and high-density optical fiber transmission has become more and more urgent. It has become inevitable to expand a one-dimensional optical fiber array into a two-dimensional optical fiber array (2D fiber array, that is, optical fiber array).
Applications: Planar optical waveguides, arrayed waveguide gratings, active/passive array fiber devices, micro-electromechanical systems; multi-channel optical modules.
