Cryo-optical microscopies, including photoluminescence and Raman microscopies, photon-correlation-functions, optically detected magnetic resonance, Rabi, T1, and T2 measurements, are used to probe temperature dependent properties of materials and quantum photonic systems.
Applications
This microscope is regularly used for applications spanning temperature and polarization dependent Raman microscopy, photon antibunching measurements, and spin-based quantum sensing.
