抄録

Nontrivial multipass interference fringes are found in the photoluminescence spectra taken from a single-quantum-well structure in the backscattering geometry. Fringe spacing indicates light interference within the 3.3-µm-thick capping layer, whereas the transmission spectra apparently lack the corresponding fringes. This indicates that an otherwise unlikely detour of photons towards the rough backside of the 350-µm substrate is relevant, which gives rise to a 3.3-µm-thick ghost cavity. The visibility of such ghost-cavity fringes is the largest for a single emission layer and is even enhanced by forward-scattering, which can facilitate light-emitter design rather than compromising the peak assignment of spectra.
