Abstract:
1. An all optical chopping device for shaping and reshaping comprising: an optical splitter having an input terminal and first and second output terminals; and an all optical AND logic gate having first and second inputs associated with said first and second output terminals, respectively, and at least one output, wherein one of said first and second inputs includes an optical delay line, wherein said splitter is arranged to receive an optical input signal from said input terminal and to split the optical input signal into first and second optical signal components to exit at said first and second output terminals, respectively, wherein said AND logic gate is arranged to receive said first and second optical signal components via said first and second inputs, and to produce at said output an optical output signal corresponding to a portion of the AND product of said first optical signal component and said second optical signal component, said optical output signal being narrower than said optical input signal.
