Paper Abstract

We demonstrate an integrated semiconductor ridge microcavity source of counterpropagating twin photons at room temperature in the telecom range. Based on type II parametric down conversion in a counterpropagating phase matching scheme with transverse pump, the device generates around 10-11 pairs/pump photons having a 0.3 nm bandwidth for a 1 mm long waveguide. The emission spectrum shows the existence of two equally probable processes, which is a preliminary step to the direct generation of Bell states. The twin character of the photons of each pair is demonstrated via a temporal correlation measurement. These results open the way to the demonstration of several interesting features associated to the counterpropagating geometry, such as the control of the frequency correlation degree via the spatial and spectral properties of the pump beam.
