Is this true, An optical top hat pulse generator controlled by solitons. The top hat generator comprises a non-linear optical loop mirror (NOLM) that is fed by a continuous wave (CW) optical signal and is controlled by incoming optical pulses comprising first order solitons. The soliton regime for the incoming optical pulses is obtained by choosing a fiber with the correct dispersion and by adjusting the peak power of the control pulses.
