Abstract
A tunable plasmonic random laser based on emitters coupled to plasmonic resonant nanocavities is demonstrated by Junxi Zhang, Fei Wang, Zhijia Hu and co-workers (see article number 2200426). The random laser with a low threshold, excited over threshold in comparison with the wide and weak emission below threshold, results from plasmon resonance energy transfer, enhanced localized electric fields, and multiple light scattering from the disorder–order hybrid silver nanorod arrays. The lasing wavelength can be tuned by harmonic modes of the nanocavities.
