Abstract

We report a strong increase in the intensity of spontaneous emission from erbium ions embedded into an active layer of amorphous silicon oxide (a-SiO x ) in a planar microcavity based on a-Si:H/a-SiO x layers. Using eigenmodes of this microcavity both for excitation (pumping) and for the extraction of photoluminescence, it is possible to increase the spontaneous emission intensity from erbium ions by a factor of about 500 as compared to the photoluminescence from a single doped a-SiO x (Er) film.
