A novel form of optical screw dislocation based on localized surface-plasmon modes (SPMs) is described. In particular, we show that a metallic sheet in the form an infinitesimally thin film deposited on a planar dielectric substrate creates surface-plasmon modes due to evanescent Laguerre-Gaussian (LG) light. The characteristic property of such a mode is the exponential decay with distance normal...
Sub-wavelength gratings are used in the new photodetector in this paper. The detectivity is enhanced by excitation of surface plasma waves (SPW) using a Metal Aperture Arrays grating. Sub-wavelength dielectric grating is used to replace the top Bottom Distributed Bragg Reflectors(DBR).
In this paper, light modulation efficiency using surface plasmon polariton (SPP) excitation in metal/electro-optic material interface is investigated by electromagnetic simulations. The propagation constant of the plasmon wave are controlled by an electric field applied across the electro-optic layer and thus modulates in magnitude the reflected light.
We demonstrate polarization control of vertical-cavity surface-emitting lasers (VCSELs) to any desired directions by utilizing surface plasmon resonance at a metal nanohole array. A silver nanohole array is integrated on the p-type distributed Bragg reflector of an 850-nm AlGaAs-GaAs-based VCSEL. The metal nanohole array placed at rectangular lattices with orthogonally different two periods, one of...
