Coherent perfect rotation
Two classes of conservative, linear, optical rotary effects (optical activity andFaraday rotation) are distinguished by their behavior under time reversal. Faraday rotation, but not optical activity, is capable of coherent perfect rotation, by which wemean the complete transfer of counterpropagating coherent light fields into their orthogonal polarization. Unlike coherent perfect absorption, ho...
متن کاملPerfect coupling of light to surface plasmons by coherent absorption.
We show theoretically that coherent light can be completely absorbed and transferred to surface plasmons in a two- or three-dimensional metallic nanostructure by exciting it with the time-reversed mode of the corresponding surface plasmon laser ("spaser"). The narrow-band perfect absorption is a generalization and application of the concept of critical coupling to a nanocavity with surface plas...
متن کاملCoherent perfect nanoabsorbers based on negative refraction.
Based on both analytical dipole model analyses and numerical simulations, we propose a concept of coherent perfect nanoabsorbers (CPNAs) for divergent beams. This concept makes use of the properties of a slab with negative refraction and small losses. The proposed CPNA device would allow focusing radiation in nanoscale regions, and hence could be applied in optical nanodevices for such diverse ...

متن کاملDegenerate four-wave interferences and perfect blaze
We present a simple model for understanding the perfect blaze for diffraction with echelle gratings. Littrow diffraction at grating profiles with rectangular apexangles implicates two pairs of counterpropagating light waves. The four waves show a rectangular pattern of interference fringes. Integer numbers of such fringes along both facets of a groove ensure perfect blazing with echelle gratings.
