New publication ! LQNO measures heat transport using quantum sensors in suspended diamond nanostructures.
We report a method to spatially resolve heat transport in suspended diamond nanostructures by integrating nitrogen-vacancy (NV) center spin defects as local thermometric probes. In our paper, “Imaging Heat Transport in Suspended Diamond Nanostructures with Integrated Spin Defect Thermometers,” we combine nanoscale device engineering and nanoofabrication with quantum sensing to obtain highly detailed maps of (…)
LQNO at Swiss NanoConvention 2025
LQNO research group participated in the Swiss NanoConvention 2025 conference held in Brugg AG, presenting two posters on the fabrication of ultra-thin diamond membranes for photonics and quantum sensing, and on entangled photon-pair generation enhanced by 2D heterostructures. Our showcases the advanced capabilities in microfabrication available to research groups in Swiss institutions, and their applications in (…)
Mode-Specific Coupling of Nanoparticle-on-Mirror Cavities with Cylindrical Vector Beams
We demonstrate selective excitation of nanocavity modes controlled by the polarization and frequency of a laser beam. More precisely, we record confocal maps of Raman scattering excited by cylindrical vector beams, which are compared to the known excitation near-field patterns. Our measurements reveal the transverse vs. longitudinal polarization of the excited antenna mode and how (…)
