Abstract

We demonstrate exciton lasing in sub-wavelength coupled nanostructures at ultralow fluence threshold, as probed by femtosecond broadband emission and absorption spectroscopy. The complex spectrotemporal dynamics reveal for the first time an excitonic-to-electron-hole plasma lasing mechanism.
