Packagable free-space optical crossbar network based on bypass-exchange switch

摘要

A packagable free-space two-dimension optical crossbar network is described, and extended to three-dimension physical space. The interconnection between two neighbor switch stages is implemented only use a calcite slab and the bypass-exchange switch is also integrated in a LiNbO3 slice. So a basic building block only consists of a bypass-exchange switching array or matrix for processing and a calcite slab for optical interconnection. A packaged crossbar network can be constructed by cascading such building blocks. The signal-to-noise ratio and cascadability of the network are discussed. It is shown that the crossbar network is compact configuration, solid state, low energy loss, easy to cascade and assemble, and insensitive to disturbance. [References: 12]
