Surface-Plasmon Holography

Surface-plasmon wavefront and spectral shaping by near-field holography

A R TI CL E Abstract Surface-plasmon-polariton waves are twodimensional electromagnetic surface waves that propagate at the interface between a metal and a dielectric. These waves exhibit unusual and attractive properties, such as high spatial confinement and enhancement of the optical field, and are widely used in a variety of applications, such as sensing and subwavelength optics. The ability...

Simultaneous amplitude-contrast and phase-contrast surface plasmon resonance imaging by use of digital holography

The surface plasmon resonance imaging technique provides a tool that allows high-throughput analysis and real-time kinetic measurement. A simultaneous amplitude-contrast and phase-contrast surface plasmon resonance imaging method is presented. The amplitude-contrast and phase-contrast images are simultaneously obtained by use of digital holography. The detection sensitivity of amplitude-contras...

Holography of BPS surface operators

We study a class of dilatation invariant BPS surface operators in 4-dimensional N = 4 Super Yang-Mills theory and their holographic duals in type IIB string theory in AdS5×S. First we take an example of 1/4 BPS surface operator and study it in detail from the holographic point of view. The gravity dual of this surface operator is a D3-brane characterized by a holomorphic submanifold. The supers...

Surface plasmon resonance biosensor

Semiconductor surface plasmon sources.

Surface-plasmon polaritons (SPPs) are propagating electromagnetic modes bound at a metal-dielectric interface. We report on electrical generation of SPPs by reproducing the analogue in the near field of the slit-doublet experiment, in a device which includes all the building blocks required for a fully integrated plasmonic active source: an electrical generator of SPPs, a coupler, and a passive...
