Abstract
A semiconductor ridge microcavity is designed to generate counterpropagating twin photons by parametric fluorescence. This device is suitable as a narrow bandwidth source of twin photons at 1.55 μm working at room temperature. A sensible efficiency improvement due to the presence of the vertical cavity is demonstrated. The degree of frequency correlation can be controlled through the pump field spatial and spectral profiles.
