Subwavelength-structured polarization-selective surfaces

چکیده
Subwavelength-period gratings exhibit a number of interesting polarization-selective properties. We investigate several such phenomena: an "inverse" wire-grid polarizer, which transmits TE light while stopping TM light, a guided-mode resonance filter with an order-of-magnitude difference in the width of the reflectance peak for the two orthogonal states of polarization, a metal-coated silicon grating that reflects only TM-polarized light while absorbing the TE-polarized field component, and a metallic polarizing beamsplitter.

Polarization conversion cube-corner retroreflector.
Polarization conversion cube-corner retroreflectors rotate the major axis of the incident electric field by 90°. We show that polarization conversion cube-corner retroreflectors cannot be created with isotropic reflecting surfaces, but can be created by incorporating nonisotropic reflecting surfaces. Two types are considered-cube corners with surfaces having elliptical eigenstates and cube corn...
متن کاملPhotonic spin Hall effect in hyperbolic metamaterials for polarization-controlled routing of subwavelength modes.
The routing of light in a deep subwavelength regime enables a variety of important applications in photonics, quantum information technologies, imaging and biosensing. Here we describe and experimentally demonstrate the selective excitation of spatially confined, subwavelength electromagnetic modes in anisotropic metamaterials with hyperbolic dispersion. A localized, circularly polarized emitte...
متن کاملBifocal Fresnel lens based on the polarization-sensitive metasurface
Thin structured surfaces allow flexible control over propagation of electromagnetic waves. Focusing and polarization state analysis are among functions, required for effective manipulation of radiation. Here a polarization sensitive Fresnel zone plate lens is proposed and experimentally demonstrated for GHz spectral range. Two spatially separated focal spots for orthogonal polarizations are obt...
متن کاملAntibonding plasmon mode coupling of an individual hole in a thin metallic film
The polarization dependence of the optical properties of individual subwavelength holes in a thin metallic film is studied using terahertz time-domain spectroscopy. We show that for parallel polarization of the incident light, the coupling is predominantly to short-range bonding film plasmons while for perpendicular polarization the incident light couples more efficiently to long-range antibond...
متن کاملExperimental realization and modeling of a subwavelength frequency-selective plasmonic metasurface
We have modeled, fabricated, and characterized a plasmonic metasurface with subwavelength features, whose dominant resonance is the independent of incident angle and polarization, and sensitive only to the material composition and geometry of a single element. Higher-order resonances, associated with surface plasmon polariton (SPP) coupling and higher diffraction orders, are sensitive to the in...
