Seeing the Unseen -- Boosted Absorption Imaging and Spectroscopy Using a Scanning Microresonator
Jonathan Noé, Michael Förg, Manuel Nutz +5
Optical detection of nanoscale objects without relying on fluorescence is a current challenge due to their extremely weak interaction with light. Resonator-enhanced absorption micr…
Ultra-Sensitive Extinction Measurements of Optically Active Defects in Monolayer MoS
Florian Sigger, Ines Amersdorffer, Alexander Hötger +12
We utilize cavity-enhanced extinction spectroscopy to directly quantify the optical absorption of defects in MoS generated by helium ion bombardment. We achieve hyperspectral i…
Cavity-enhanced Raman Microscopy of Individual Carbon Nanotubes
Thomas Hümmer, Jonathan Noe, Matthias S. Hofmann +3
Raman spectroscopy reveals chemically specific information and provides label-free insight into the molecular world. However, the signals are intrinsically weak and call for enhanc…
Highly coherent electron beam from a laser-triggered tungsten needle tip
Dominik Ehberger, Jakob Hammer, Max Eisele +4
We report on a quantitative measurement of the spatial coherence of electrons emitted from a sharp metal needle tip. We investigate the coherence in photoemission using near-ultrav…
