Optical field enhancement at cusps between adjacent nanoapertures.
Optical nonlinear properties of cusps formed at the junction between two circular apertures in a metal film have been studied by scanning confocal microscopy. For gold, both second harmonic and broadband emission are enhanced when the pump polarization is directed across the gap between cusps, similar to the behavior of the recently studied bowtie antennas and apertures. However, field enhancem...
متن کاملInfluence of Grating Parameters on the Field Enhancement of an Optical Antenna under Laser Irradiation
In this study, a new approach for simulation of electric field enhancement ofplane wave laser around optical antenna was used to convert free-propagating opticalradiation to localized energy. A tapered gold tip design as a novel geometry of opticalantenna is introduced and numerically analyzed based on particle swarm optimization(PSO) by solving the Maxwell equations wit...
متن کاملField enhancement in apertureless near-field scanning optical microscopy.
The near field of an apertureless near-field scanning optical microscopy probe is investigated with a multiple-multipole technique to obtain optical fields in the vicinity of a silicon probe tip and a glass substrate. The results demonstrate that electric field enhancements of >15 relative to the incident fields can be achieved near a silicon tip, implying intensity enhancements of several orde...
متن کاملOptical field enhancement factor of Silicon and indium phosphide nano-cavities
Nano cavities based on silicon and indium phosphide materials have been comparedin this study, considering field intensity enhancement factor. The results of FDTD based simulations declare that the Si nano-cavity improves confined optical field about 7.7 times higher than the InP based nano-cavity. The introduced dielectric nano-cavities support resonance wavelength at about λ=1.55 μm.
متن کاملNear-field interaction between domain walls in adjacent Permalloy nanowires.
The magnetostatic interaction between two oppositely charged transverse domain walls (TDWs) in adjacent Permalloy nanowires is experimentally demonstrated. The dependence of the pinning strength on wire separation is investigated for distances between 13 and 125 nm. The results can be described fully by considering the distribution of magnetic charge within rigid, isolated TDWs. Alternative DW ...
