Towards few photon bifurcations in coupled nanocavities

Alejandro M. Yacomotti, Bruno Garbin, Juan A. Levenson

CNRS, France

Nanopotonic dimers are appealing test-beds for few photon optical nonlinearities in the context of nonlinear and quantum optics. In this talk I will focus on two evanescently coupled semiconductor photonic crystal nanocavities, which can be engineered to experimentally access bifurcation points. I will discuss two key bifurcations: spatial (pitchfork) leading to localized states in the dimer, and temporal (Hopf) symmetry breaking leading to mesoscopic limit cycles. These observations rely on the high degree of intercavity coupling control, making our platform an ideal one for the investigation of few photon bifurcations.

By increasing the number of dipoles and optimizing the spatial overlap with the photonic field, the light-matter coupling can become strong enough to modify the materials’ electronic properties. We first predicted, and then experimentally demonstrated that, in cavity-embedded doped quantum wells, light-matter coupling allows for the creation of novel excitonic bound states in which electrons and holes are bound together by the exchange of cavity photons . Such a cavity-stabilised state is spectroscopically observed as a discrete resonance appearing below the ionisation threshold.

Indistinguishable photons from a single molecule under pulsed excitation

Quantum light sources are crucial for the future of quantum photonic technologies. Ideal quantum emitters providing indistinguishable photons in a clocked manner with negligible decoherence and spectral diffusion, as well as high brightness and with potential for scalability are today still a major challenge. We report on photostable and indistinguishable single-photon emission from dibenzoterrylene molecules isolated in anthracene nanocrystals (DBT:Ac NCs) at 3K. The visibility of two-photon interference is preserved even when they are separated more than thirty times the excited-state lifetime or ten fluorescence cycles.

Surface-generated polarization-entangled photons

We demonstrate the generation of polarization-entangled photons in a subwavelength layer of (100)-GaAs. We reconstruct the photon pair polarization state and show that it can be generated only due to the surface nonlinear response of GaAs. We also investigate the surface nonlinearity using second-harmonic generation.
