Surface plasmon amplification by stimulated emission of radiation (spaser) is a nanoscopic quantum generator of coherent local optical fields with high intensity. We will consider the latest development in the theory of spaser and review the large number of experimental data currently available Nanoplasmonics deals with collective electron dynamics on the surface of metal nanostructures, which arises...
A conical micromirror is shown to increase the signal from fluorescent molecules within a collocated subwavelength metal aperture by 5×. Large-scale integration (75,000 miromirrors/aperture pairs) is demonstrated.
We report efficient non-imaging emission collection optics for compact fluorescence detection systems. A combination of hemispherical dome mirrors redirects and integrates the isotropic fluorescent emission toward the photodetector, and significantly enhances the fluorescence signal level.
Early-generation waveguide arrays made of silicon (Si) and fused silica (SiO2) were micromachined for infrared (IR) neural stimulation and optogenetics applications in able to provide comprehensive and selective access to distributed targets. Edge-coupled multimode fibers delivered light through the optrodes. Maximum normalized output power from the tips, with respect to the fiber output, was determined...
