Ultrastrong Light-Matter Coupling in Materials
Niclas S. Mueller, Eduardo B. Barros, Stephanie Reich
Ultrastrong light-matter coupling has traditionally been studied in optical cavities, where it occurs when the light-matter coupling strength reaches a significant fraction of the…
Full Crystallographic Imaging of Hexagonal Boron Nitride Monolayers with Phonon-Enhanced Sum-Frequency Microscopy
Niclas S. Mueller, Alexander P. Fellows, Ben John +13
Hexagonal boron nitride (hBN) is an important 2D material for van der Waals heterostructures, single photon emitters, and infrared nanophotonics. The optical characterization of mo…
Electro-Optic Cavities for In-Situ Measurement of Cavity Fields
Michael S. Spencer, Joanna M. Urban, Maximilian Frenzel +5
Cavity electrodynamics offers a unique avenue for tailoring ground-state material properties, excited-state engineering, and versatile control of quantum matter. Merging these conc…
Anti-Stokes Photoluminescence in Monolayer WSe Activated by Plasmonic Cavities through Resonant Excitation of Dark Excitons
Niclas S. Mueller, Rakesh Arul, Ashley P. Saunders +9
Anti-Stokes photoluminescence (PL) is light emission at a higher photon energy than the excitation, with applications in optical cooling, bioimaging, lasing, and quantum optics. He…
