Femtosecond surface plasmon interferometry.

چکیده
We demonstrate femtosecond plasmonic interferometry with a novel geometry. The plasmonic microinterferometer consists of a tilted slit-groove pair. This arrangement allows for (i) interferometric measurements at a single wavelength with a single microinterferometer and (ii) unambiguous discrimination between changes in real and imaginary parts of the metal dielectric function. The performance is demonstrated by monitoring the sub-picosecond dynamics of hot electrons in gold.

Group delay and dispersion in adiabatic plasmonic nanofocusing.
We study the decrease in group velocity of broadband surface plasmon polariton propagation on a conical tip, using femtosecond time-domain interferometry. The group delay of (9±3) fs measured corresponds to a group velocity at the apex of less than 0.2c. The result agrees in general with the prediction from adiabatic plasmonic nanofocusing theory, yet is sensitive with respect to the exact tape...
متن کاملFemtosecond nonlinear ultrasonics in gold probed with ultrashort surface plasmons.
Fundamental interactions induced by lattice vibrations on ultrafast time scales have become increasingly important for modern nanoscience and technology. Experimental access to the physical properties of acoustic phonons in the terahertz-frequency range and over the entire Brillouin zone is crucial for understanding electric and thermal transport in solids and their compounds. Here we report on...

متن کاملAn Accelerated Approach to Sensitive ADA Assays
The performance of an antibody in an assay often correlates with its affinity to the antigen. The ability to specifically select for antibodies on the basis of binding strength is therefore an important element of antibody assay development. Affinity or koff-rate determination can be carried out on several platforms; for example a rough ranking by ELISA, or quantitative screening using a techno...
متن کاملA Small-Displacement Sensor Using Total Internal Reflection Theory and Surface Plasmon Resonance Technology for Heterodyne Interferometry
A small-displacement sensor based on total-internal reflection theory and surface plasmon resonance technology is proposed for use in heterodyne interferometry. A small displacement can be obtained simply by measuring the variation in phase difference between s- and p-polarization states with the small-displacement sensor. The theoretical displacement resolution of the small-displacement sensor...
