dc.description
In recent years, cathodoluminescence in scanning electron microscopy has seen a growth in interest. From phase-locked photon-electron interactions [1] or indirect electron
excitations [2] to probing photonic local density of states in nano waveguides [3]. We present an experimental setup, where we generate coherent cathodoluminescence utilizing
the Cherenkov effect in the scanning electron microscope. To fulfil the Cherenkov condition nβ > 1 in the SEM (βe = 0.33c), a 3 μm thick silicon slab (n = 3.8) is placed onto the
facete of a multi-mode optic fibre, which is guided out of the SEM with a fibre feedthrough. We want to perform two different measurements: photon bunching using a Hanbury
Brown - Twiss interferometer [4,5], and electron-photon correlations [6] using an Everhart–Thornley or backscattered electron detector and a single photon detector. We
characterize the CL photons by tuning the acceleration voltage below/above the Cherenkov threshold condition and investigate the signal in g²(τ ) measurements.
