OPTICAL SWITCH Russian patent published in 2012 - IPC G02F1/295 

FIELD: physics.

SUBSTANCE: device has n optical flux switching units, each having m pairs of optically coupled waveguides, m photodetectors and m piezoelectric elements into which m pairs of optically coupled waveguides are integrated. The switch also has (m+1) optical n-input couplers. The j-th data input of the optical switch is the data input of the j-th optical flux switching unit. The address inputs of the optical switch are the corresponding address inputs of n optical flux switching units.

EFFECT: high speed of operation, simple design of the device, possibility of switching each of the n optical fluxes on data channels in fibre-optic information transmission systems.
