主　　题：band lasing driving 

摘      要：Surface lattice resonances(SLRs)with ultra-narrow linewidth(high quality factor)can enhance light–matter interactions at the nanoscale and modulate the propagating light from the emission wavelength direction to efficiency by photonic band ***,SLRs can serve as an excited candidate to enhance and,more importantly,modulate amplified spontaneous emission(ASE)with more optical ***,this work presents a system of two-dimensional Ag-coated Al nanocone array(Ag-NCA)packaged with Nile red,and a normal ASE with 15-fold enhancement is observed under external driving *** enhancement fades away,obviously,in the case of the off-normal condition,as the optical feedback evolves from the band edge steady state to the propagating *** ASE of this hybrid plasmonic system expands the possibilities of interaction between light and matter and has great promise for applications in nanolasing,super-resolution imaging,and photonic integration circuits.
