Abstract

The invention relates to a 3*3 free-space optical router, which comprises six beam channels, eighteen polarization beam splitters, nineteen optical switches and nineteen electrical switches which are integrated on one circuit control board, wherein one end of each optical switch is connected with a power supply, and the other end of each optical switch is connected with the other end of the power supply through the corresponding electrical switch; and the control end of each electrical switch is connected with the output end of a computer through a data line. The computer can realize non-blocking connection between any two channels of the six channels by controlling the polarization state of signal light. The router provided by the invention has the advantages of simple structure, fast response, non-blocking connection, high-speed parallel, high capacity and the like, and is suitable for various optical interconnection networks.

Description

technical field [0001] The invention relates to an optical router, in particular to a 3*3 free-space optical router, which can quickly realize the simultaneous non-blocking connection between any two channels in six channels. It is suitable for various optical interconnection networks and space laser communication. Background technique [0002] Large-bandwidth optical interconnection and optical switching technology with fast switching capability has great application prospects in computer and optical communication systems, so it has become the frontier and hot spot of information optics research and development. The optical interconnection network is derived and developed from the electronic interconnection network, and the topology of the network is realized by the optical interconnection and the optical switch array. Due to the "bottleneck" of electronic circuit bandwidth, which limits the throughput of network nodes, optical switches are crucial to the functional realiz...
