Figure 4: Hyperspectral maps.
From: Switching and amplification in disordered lasing resonators
Each map is obtained by fixing the indicated detection wavelength. Panel a is relative to the configuration S:ON; G:OFF and shows the spatial extent of the source mode. Panel b shows S:OFF; G:ON, that is, the D mode that lies in and around where drain spectra are measured. Panels c and d are relative to the S:ON; G:ON configuration for the S and for the D modes, respectively.
