Monobloc crystal integrated free space type vertical and horizontal network

Abstract

The criss-cross network includes one parallel hexahedron crystal, N input optical paths in the light beam input plane and N output optical paths in the light beam otuput plane, with N being not small than 3. Each of the input optical paths is provided with input fiber, collimator and polarizer; and each of the output optical paths is provided with focusing lens and output fiber. The present invention features that all electrode pairs are integrated in the first electrode plane and the second electrode plane of the crystal; all the electrode pairs are parallel; all the electrodes have length direction in the optical axis direction of the crystal; and all the electrode pairs are divided into m switch levels and in the equal distance of D, with the adjacent switch levels being separated by distance DeltaL. The present invention integrates all the optical switches in the same crystal and can realize the crossbar interconnection of all the inputs and all the output.

Description

Technical field: [0001] The invention relates to an optical interconnection network, in particular to a free-space crossbar network integrated with a single crystal, which is the simplest optical interconnection network and is applied to communication networks, optical computing and other parallel processing systems, etc. field. Background technique: [0002] As an important part of communication network, multiprocessor system and other parallel processing structures, interconnection network has been extensively studied. Various effective interconnection methods have been proposed according to different needs, such as Shuffle network, Butterfly network, Crossbar network, and Omega network. , Banyan network, etc. Among them, the Crossbar network is the simplest and easiest to implement. Due to the advantages of optics in high parallelism, large capacity, and high bandwidth, people are working to replace traditional electronic interconnection networks with optical interconnec...

Problems solved by technology

[0007] In short, in the prior art, the waveguide-type Crossbar network light beam is bound in the waveguide, the network capacity is limited, and the speed is slow

In order to realize the interconnection between the two switching stages in the free-space Crossbar network, multiple discrete components are required, which increases the energy loss of the light beam in practical applications, and the components are not easy to install and calibrate, and the network’s anti-interference ability is poor.
