Scanning near-field microscopy of microdisk resonator with InP/GalnP quantum dots using cantilever-based probes

Cathodoluminescence hyperspectral analysis of whispering gallery modes in active semiconductor wedge resonators

“…Most demonstrations of WGM cathodoluminescence images have been demonstrated with wide band gap materials such as GaN [12] and ZnO [13] while recourse to HCL remains anecdotal [5]. Conversely, recent results using scanning near-field microscopy on InP-based microdisks [14] demonstrate the vivid interest in imaging WGMs at the sub-wavelength resolution.…”
