Plasmonics: Metal–Dielectric Core–Shell Nanoparticles: Advanced Plasmonic Architectures Towards Multiple Control of Random Lasers (Advanced Optical Materials 8/2013)




Metal–dielectric core–shell nanoparticles serve as robust platforms for control of light-matter interactions via chemically accessible tunability of the dielectric shell thickness. Now X. Meng, K. Fujita, et al. have applied such platforms to the area of random lasers, and on page 573 they demonstrate control of lasing in terms of pump threshold, output power, lasing spikiness, and mode interactions by varying the shell thickness. This plasmonic approach opens up new avenues towards well-controlled random lasers.
