Deep subwavelength optical imaging using correlated nano-torches


The authors propose and numerically demonstrate an ultra-high resolution (wavelength/50∼40 nm at wavelength λ=2.08 μm, high-throughput (∼66%), and non-destructive optical lens with a large contrast-to-noise ratio, based on the notion of correlated nano-torches formed in a subwavelength metallic grating. The correlations between the torches also allow the determination of the complex refractive index of the sample.
