Paper Abstract

The miniaturization of quantum information technology is a subject attracting a growing attention. The exploitation of spontaneous parametric down conversion in AlGaAs waveguides to generate photon pairs presents several advantages: high nonlinear susceptibility, room-temperature operation and high emission directionality in the telecom range. In this work we will present our recent results on three different kinds of AlGaAs devices: a selectively oxidized source based on form birefringence, a waveguide based on modal phase matching and a microcavity-based source based on counterpropagating phase matching. We will discuss and compare the figures of merit characterizing the three devices for quantum communication applications.
