OPTICAL ANALOGUE NANO-DEMULTIPLEXER Russian patent published in 2010 - IPC G02F7/00 B82B1/00 

FIELD: physics.

SUBSTANCE: nano-demultiplexer has an optical M-output nanofibre splitter, M optical nanofibres, M optical output nanofibres, two extensible nanotubes, a source of constant optical signal, an optical nanofibre N-output splitter, a control optical nanofibre, an optical nanofibre N-input splitter. The two extensible nanotubes lie between the output of the control optical nanofibre and the output of the optical N-input nanofibre coupler such that, in the extreme left-handed position, an inner nanotube opens optical connection between outputs of the N-output optical nanofibre splitter and inputs of the N-input optical nanofibre coupler, as well as between outputs of the M-output nanofibre splitter and inputs of the M optical nanofibres. There is no optical connection between outputs of the M optical nanofibres and inputs of the M optical outputs of the nanofibres.

EFFECT: faster operation, simple design and nano-size implementation.
