Harmonic Generation and Wave Mixing in Confinement Structures: An Account of Pump Depletion in Second-Order Nonlinear Multilayer Microcavities

Figure 5

Effect of incident-pump-wave intensity on pump depletion, versus wavelength. Continuous (blue) curve: pump depletion neglected; dashed (red) curve: pump depletion taken into account. (a) “weak” incident-pump-wave intensity (5,31 GW/m² or 2,0 MV/m). The inset is a zoom-in on the central peak. (b) “Intermediate” incident-pump-wave intensity (53,1 GW/m²). (c) “Strong” incident-pump-wave intensity (531 GW/m²).
