Semiconductor Quantum Photonics

Combining quantum confinement of excitons and optical confinement of photons in nanostructures allows to achieve the ultimate control of light-matter interaction. By devising quantum wires and quantum dots of specific configurations and integrating them into optical microcavities, we explore the generation of new states of lights, including single photons, correlated photons and photon entanglement.
