Integrated quantum photonics is a very active field of quantum information, communication, and processing. One of
the main challenges to achieve massively parallel systems for complex operations is the generation, manipulation, and
detection of many qubits within the same chip. Here, we present our last achievements on AlGaAs quantum photonic
devices emitting nonclassical states of light at room temperature by spontaneous parametric down conversion (SPDC).
The choice of this platform combines the advantages of a mature fabrication technology, a high nonlinear coefficient, a
SPDC wavelength in the C-telecom band and the possibility of electrical injection.
