A. Mlayah et al., OPTICAL AMPLIFICATION OF RAMAN-SCATTERING IN A GAAS BULK MICROCAVITY, Journal of physics. Condensed matter (Print), 10(42), 1998, pp. 9535-9540
We present photoluminescence, reflectivity and Raman scattering measur
ements on a GaAs Fabry-Perot bulk microcavity. A strong enhancement of
the Raman scattering efficiency is observed when either the incident
or the scattered photons are tuned to the cavity mode. Resonance curve
s are obtained for scattering by both transverse and longitudinal opti
cal phonons, and analysed in terms of the optical amplification due to
confinement of the electromagnetic field. Resonance effects as strong
as that observed in microcavities with embedded quantum wells are obs
erved. Single and double resonance Raman profiles are calculated and a
good agreement with measurements is obtained.
