Quantum light-matter interfaces at the nanoscale
We couple solid-state quantum emitters (semiconductor nanocrystals, nanodiamonds) to tapered optical nanofibers and photonic waveguides, to realize efficient single-photon sources and to control light matter interaction at the single-photon level.
Our research lies at the interface of quantum optics, nanophotonics, and solid-state physics. We study how confining light in optical nanofibers and photonic waveguides modifies its interaction with individual quantum emitters.
By coupling guided optical modes to semiconductor nanocrystals, color centers in nanodiamonds, and other solid-state emitters, we aim to control the emission, propagation, and quantum properties of light at the nanoscale. These hybrid systems provide a platform for investigating light-matter interactions in one-dimensional photonic systems and for developing integrated sources and processors of non-classical light.
What we work on
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.
High-quality single-photon emitters
We develop and characterize high-quality single-photon emitters — from perovskite and semiconductor nanocrystals to color centers in diamond (bulk and nanodiamonds) and quantum dots — searching for bright, room-temperature-compatible sources.
Quantum emitters coupled to optical nanowaveguides
We couple single colloidal quantum emitters to optical nanowaveguides such as tapered optical nanofibers, collecting their emission into a single guided mode toward compact integrated single-photon sources.
