Four-wave mixing frequency domain

FIGURE 16 Frequency response of four-wave mixing in an SOA. (a) Schematic arrangement of the frequency domain pump-probe measurement, (b) Four-wave mixing conversion efficiency as a function of pump-probe detuning. 

Figure 16 shows the results of an experimental measurement of the frequency response of the four-wave mixing process in an SOA. The experimental technique used is a frequency domain pump-probe measurement, illustrated schematically in Fig. 16(a). Two optical carriers are injected into the SOA, a strong pump signal Pp and a much weaker probe signal Pq. The frequency detuning is defined to be the probe frequency minus the pump frequency, i.e., The power Ps of the...
