High-efficiency low-crosstalk dielectric metasurfaces of mid-wave infrared focal plane arrays
High-resolution compact-size focal plane arrays (FPAs) suffer the fundamental geometrical tradeoff between the optical resolution (pixel size miniaturization) and the optical crosstalk (spillover of neighboring pixel ...
High-efficiency and low-loss gallium nitride dielectric metasurfaces for nanophotonics at visible wavelengths
The dielectric nanophotonics research community is currently exploring transparent material platforms (e.g., TiO2, Si3N4, and GaP) to realize compact high efficiency optical devices at visible wavelengths. Efficient ...
Spectral tunability and enhancement of molecular radiative emission by metal-dielectric-metal stratified plasmonic nanostructure
Plasmonic nanostructures have been widely known for their notable capability to enhance spontaneous emission of an electric dipole in their vicinity. Due to the availability of large optical density of states at their ...
