Multiple wavelength coding optical switch array

Abstract

Several optical fibers and an optical wave separator constitute n independent light paths of different wavelengths, and the n independent light paths are arranged into an array via two-aperture fiber collimator. The encoding switch has one coaxial rotor of light scanner to drive one zoned encoding holoreflecting medium diaphragm, and the reflecting areas correspond to the two-aperture fiber collimator. When the reflecting areas align the end of the two-aperture fiber collimator parallelly, the two-aperture fiber collimator forms a optical path, or else, no optical path is formed. The light crossed connection is realized by means of encoding of double fiber array and reflecting areas.

Description

technical field

[0001] A multi-wavelength coded optical switch array belongs to the technical field of optical communication. Background technique

[0002] In terms of information technology, more and more information shows that after the Internet, one of the largest industries in information is photonics, which uses optical methods to carry out the Internet, with fast speed and large capacity, and replaces routers in the switching network with optical fiber devices. The interconnection of the Golden Optical Network can be realized. However, the current use of optical devices to replace the routers in the switching network still has the disadvantage of the so-called "electronic bottleneck". After the electronic cross-connection, re-realize the optical / electrical conversion and enter the optical transmission network, not only the equipment is complex, the transmission speed is slow, and the loss is large.
