Hybrid nanophotonic interfaces for quantum light
We build interfaces between photonic waveguides and solid-state quantum emitters. By coupling these systems at the nanometer scale, we aim to control single photons, engineer light–matter interaction, and explore physics that emerges only in the hybrid regime.
High-quality semiconductor and perovskite nanocrystals
Quantum dots based on II–VI semiconductor and perovskite nanocrystals can emit light at room temperature and are synthesized via wet chemistry. We characterize their emission to find room-temperature-compatible single-photon sources.
Nanophotonics structures with optical nanofibers
One of the most commonly faced problems with semiconductor single-photon sources is implementing fluorescence collection with high efficiency. We are specialized in tapered optical nanofiber engineering to collect single-photon emission.
Quantum nano-emitters coupled to nanofibers
To collect but also to probe nano-emitters, we deposit them on our tapered optical nanofiber and collect their emission in a single guided mode.
Previous activities
Hybrid Quantum Information Processing
The hybrid approach of quantum information processing consists in elaborating new quantum protocols by mixing techniques and quantum states of two traditionally separated domains: the "discrete" way of encoding information, playing on the corpuscular aspect of light, and the "continuous" way, based on the wave nature of photons.
Giant nonlinearities of emitters highly coupled to light
Quantum nanophotonics blends expertise in solid-state physics and optics, allowing highly coherent quantum dots (quasi-perfect two-level systems) to be strongly coupled to light through high-quality nanophotonic structures.
Polarization-entangled photon pairs on a silicon photonic chip
Realizing photonic circuits where photons replace electrons (circuits less sensitive to heat, with higher data-transfer rates), with one of the best sources of entangled photon pairs in semiconductors.
