We proposed and experimental demonstrated all-optical two line-four line encoder and two
bit-wise comparator of RZ data streams at 40Gb/s based on cross gain modulation (XGM) …

Logic gates are the fundamental building blocks of digital systems. Using these logic gates,
one can perform different logic and arithmetic operations. All-optical logic and arithmetic …

A frequency encoded all optical N bit comparator is proposed. The implementation is
ultrafast one and the frequency encoding makes it intensity loss dependent problem free …

An all-optical 3: 8 decoder unit with the help of terahertz optical asymmetric demultiplexer
(TOAD) is proposed. The all-optical 3: 8 decoder unit with a set of all-optical full-adders and …

Modern communication technologies need huge operational speed. This will be achieved if
a standard data service, ie electron, is substituted by photon for the devices which are …

A verbal exchange today wishes for quick operational progress. This can be accomplished
by replacing devices that are primarily concerned with commutation and logic with photon …

ABSTRACT A novel scheme for an ultrahigh-speed all-optical full adder based on dual-
pump four-wave mixing (FWM), including parallel dual-pump FWM and orthogonal dual …

A compact configuration of all-optical adders implemented with a single semiconductor
optical amplifier (SOA) and optical bandpass filter (OBF) is presented in this paper. A …
