- In this Letter, we report on dark field imaging of localized surface plasmon polaritons (SPPs) in plasmonic waveguiding bands formed by plasmonic coupled cavities. We image the light scattered from SPPs in the plasmonic ...
- Spatial coherence of random laser emission
[作者:Redding, B; Choma, MA; Cao, H,期刊:OPTICS LETTERS, 页码:3404-3406 , 文章类型: Article,,卷期:2011年36-17]
- We experimentally studied the spatial coherence of random laser emission from dye solutions containing nanoparticles. The spatial coherence, measured in a double slit experiment, varied significantly with the density of ...
- Jaynes-Cummings photonic superlattices
[作者:Longhi, S,期刊:OPTICS LETTERS, 页码:3407-3409 , 文章类型: Article,,卷期:2011年36-17]
- A classical realization of the Jaynes-Cummings (JC) model, describing the interaction of a two-level atom with a quantized cavity mode, is proposed based on light transport in engineered waveguide superlattices. The opti...
