OPTICAL SUBTRACTING NANO DEVICE Russian patent published in 2009 - IPC G02F7/00 B82B1/00 

FIELD: physics, computer facilities.

SUBSTANCE: offered invention concerns computer facilities and can be used in optical information processing devices. The offered optical subtracting nano-device contains an input optical Y-splitter, a radiant of the constant optical signal, two optical nano-fiber N-output splitters, two target optical nano-fiber a Y-splitter, two input optical nano-fiber couplers, two optical N-input nano-fiber couplers, optically interfaced among themselves in appropriate way, and two telescopic nanotubes - interior and exterior one.

EFFECT: solution of a problem of subtraction both coherent, and incoherent optical signals with speed, potentially possible for optical processor plans, and also a problem ofnanosized device implement.
