Method, device, and system for waveform shaping of signal light
The method of the present invention comprises the steps of providing a nonlinear optical loop mirror comprising a first optical coupler including first and second optical paths directionally coupled to each other, a loop optical path including first and second fibers having different characteristics for connecting the first and second optical paths, and a second optical coupler including a third optical path directionally coupled to the loop optical path; and supplying probe light and input signal light from the first and third optical paths, respectively, and outputting output signal light from the second optical path.
