Refraction index sensor based on phase resonances in a subwavelength structure with double period
(OSA - The Optical Society, 2016-10)
In this paper, we numerically demonstrate a refraction index sensor based on phase resonance excitation in a subwavelength-slit structure with a double period. The sensor consists of a metal layer with subwavelength slots ...
Control of the diffracted response of a metallic wire array with double period: experimental demonstration
(Optical Society of America, 2014-10)
In recent papers, it has been theoretically shown that by using dual-period wire gratings, it is possible to control the relative efficiencies of the diffracted orders, regardless of the wires` material, incident polarization ...
Writing saturated holograms in LiNbO3 crystals through phase control and double diffraction
(Springer, 2010-05-01)
The usual phase-controlled two-beam coupling with heavily doped LiNbO3 crystals leads to the generation of periodic states, characterized by unitary diffraction efficiencies and strong phase oscillations. The maximum ...
Recording different geometries of 2D hexagonal photonic crystals by choosing the phase between two-beam interference exposures
(Optical Soc AmerWashingtonEUA, 2006)
Tunable ytterbium-doped fiber laser based on a mechanically induced long period holey fiber grating
(2007)
We describe a tunable double-clad Yb-doped fiber laser based on a long period fiber grating mechanically induced in a section of single mode holey fiber inserted into the laser cavity. The mechanically induced long period ...
Transmission through subwavelength slit structures with a double period: A simple model for the prediction of resonances
(IOP Publishing, 2009-10)
Transmission wire gratings comprising several subwavelength slits within each period (compound gratings) have been shown to exhibit abrupt dips in the transmission response. These minima correspond to phase resonances, ...
