Rare earth doped crystals for integrated quantum photonics
prof. Philippe Goldner
CNRS - PSL University
Systems with both spin and optical transitions offer a range of functionalities for technologies such as quantum communications, computing, and sensing. Among various solid-state systems currently considered, rare-earth doped materials stand out as they combine, at cryogenic temperatures, long-lived optical and spin quantum states. In addition, they offer optical transition in a wide spectral range, including telecom wavelengths, high chemical stability, and easy doping in many hosts, thus enabling using large ensembles of centers with uniform properties.
Quantum-grade rare earth doped nanostructured materials such as nanoparticles, thin films, or molecular crystals, aiming at integration into nanophotonics devices have recently raised a strong interest. In this talk, we will present some of our recent results in the field, as well as the challenges to be addressed to bring rare-earth doped materials up to the highly demanding requirements of quantum technologies.
The seminar will be held in the Microsoft Teams application (for people from the intibs.pl domain, a dedicated invitation has been sent). Other people interested in the seminar are asked to contact prof. dr hab. Artur Bednarkiewicz ().
