Lasing and condensation in plasmonic lattices

摘要

I review our recent findings on lasing / condensation in plasmonic nanoparticle lattices. The system properties can betailored with high precision, including the lasing / condensation energies, linewidths, as well as the dimensionality of thefeedback. For a 2-dimensional (2-D) square lattice, we identify lasing in the bright and the dark mode of the system1. Byreducing the dimensionality to 1-D we observe the dark mode lasing. In broken symmetry 2-dimensional rectangularlattices, we observe multimode lasing. In honeycomb lattices with hexagonal symmetry, we observe 6 beams withspecific off-normal angles and polarization properties corresponding to six-fold symmetry of such a lattice. Finally, Ireview our recent studies in plasmonic Bose-Einstein condensation in plasmonic lattices.
