Lauret studies quantum light from low-dimensional materials - room-temperature single-photon emission from carbon nanotubes and defects in hexagonal boron nitride, coupled to photonic/plasmonic structures - a fundamental-photon and quantum-emitter platform. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work provides solid-state single-photon sources adjacent to spin-defect sensing.
Ledoux-Rak works on molecular and polymer nonlinear optics - second-harmonic generation, electro-optic modulators, and photonic materials/devices - a fundamental-light and nonlinear-photonics program (legacy LPQM at ENS Cachan). In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work connects via nonlinear-optical materials for photon-pair generation and modulation.
