R. Shimano et al., NONLINEAR-OPTICAL RESPONSES OF EXCITON-MICROCAVITY COUPLED SYSTEM IN WEAK AND INTERMEDIATE COUPLING REGIME, Journal of luminescence, 72-4, 1997, pp. 297-299
We examine the features of degenerate four-wave-mixing (DFWM) spectra
of semiconductor microcavities in the weak and intermediate coupling r
egime. By tuning the exciton energy utilizing quantum-confined Stark e
ffect, the exciton-microcavity detuning is systematically controlled.
In intermediate coupling regime, the enhancement of nonlinear signal d
oes not coincide with the normal mode resonances observed in linear re
flection spectrum. With these results, the criteria for strong couplin
g regime are discussed.
