T. Nishikawa et al., INFLUENCE OF PHOTON REABSORPTION ON THE TRANSFER EFFICIENCY OF OUTPUTINTENSITY IN SEMICONDUCTOR MICROCAVITIES, IEEE photonics technology letters, 9(2), 1997, pp. 179-181
Photon reabsorption effect on the transfer efficiency beta(t) of half-
wavelength semiconductor microcavities was investigated by examining t
he excitation intensity dependence of the output light intensity, It i
s shown that beta(t) increases under intense excitation, and approache
s to over-all spontaneous emission coupling coefficient beta(o), as a
result of the elimination of photon reabsorption, The results clearly
demonstrate that the photon reabsorption is the predominant mechanism
of the suppression of beta(t) at weak excitation, especially in the ca
se of half-wavelength high-Q cavities.
