OPTICAL ANALOGUE-TO-DIGITAL NANOCONVERTER Russian patent published in 2010 - IPC G02F7/00 G06E1/00 B82B1/00 

FIELD: physics.

SUBSTANCE: nanoconverter has a constant optical signal source, an optical nanofibre Y-junction divider, two optical nanofibre N-output dividers lying in mutually perpendicular planes, two telescopic nanotubes, an input optical nanofibre, an optical N-input nanofibre coupler and a group of N optical nanofibres. The telescopic nanofibres are arranged such that in the extreme left position the inner nanotube breaks optical connection between outputs of the first N-output optical nanofibre divider and inputs of the N-input optical nanofibre divider, as well as optical connection between outputs of the second N-output optical nanofibre divider and inputs of the group of N optical nanofibres whose outputs are outputs of the device.

EFFECT: provision for digital conversion to a weighted binary code of optical analogue signals, with fast operation which is potentially achieved for purely optical information processing nanodevices.
