Emission intensity and linewidth as functions of the pumping energy density
(a) for a nanolaser formed on the SC-Al/Al2O3template and (b) the corresponding emission spectrum. Emission intensity and linewidth as functions ofthe pumping energy density (c) for a nanolaser formed on the PC-Al/Al2O3template and (d) the corresponding emission spectrum. All the data are measured at 77 K.
