(a) The experimental setup of the pump-probe system using an externally modulated RZ-OOK data-stream based pump beam and a continue-wave signal-mode laser based probe beam. (b) The optical spectrum of the externally modulated optical pump signal. (c) The time-domain trace of the single “on-bit” data within externally modulated optical RZ-OOK data-stream based pump signal. (d) The illustration of the nonlinear optical Kerr effect induced shift on the notched resonant dip and (e) the corresponding cross-amplitude modulation on the probe signal passing through the rib/micro-ring waveguide resonator based all-optical Kerr switch.
