Constant-force photonic projectile for long-distance targeting delivery
Optically controllable delivery of microparticles excites interesting research and applications in various fields because of the noninvasive and noncontact features. However, long-distance delivery with a static low-power light source remains challenging. …
Emission dynamics and spectrum of a nanoshell-based plasmonic nanolaser spaser
We study theoretically the emission and lasing properties of a single nanoshell spaser nanoparticle with an active core and a plasmonic metal shell. Using time-dependent equations for the gain medium and metal, we calculate the lasing threshold through an …
Degeneracy mediated thermal emission from nanoscale optical resonators with high-order symmetry
Conventional thermal emitters, such as a blackbody or the incandescent filament of a light bulb, lack the directionality or narrow linewidth required in many applications such as thermophotovoltaics and infrared sensing. Although thermal emission from bulk …
