We present a combination of self-interference microscopy with lateral super-resolution microscopy and introduce a novel approach for localizing a single nano-emitter to within a few nanometers in all three dimensions over a large axial range. We demonstrat ...
The extraordinary light transmission effect (EOT) through sub-wavelength nanoapertures in opaque metal films has lead to observation of a wide variety of exciting new optical phenomena. This remarkable effect is generally related to the interaction of the ...
Motivated by the fabrication potential of multi-walled carbon nanotube structures, we numerically investigated a paired structure consisting of two metallic spheres each grown on one end of a multi-walled nanotube. The paired two-segmented structure is cap ...
The Optical trapping of Au nanoparticles with dimensions as small as 10 nm in the gap of plasmonic dipole antennas is demonstrated. Single nanoparticle trapping events are recorded in real time by monitoring the Rayleigh scattering spectra of individual pl ...
This work focuses on trapping subwavelength objects using resonant plasmonic structures. Trapping entities include latex spheres, living cells and metallic particles; the plasmonic structures involved include subwavelength disks, subwavelength apertures, a ...
A complete realization of an optically tunable true time delay, generated through the combination of a photonic RF phase shifter and a Brillouin slow light element is presented. Illustration through a dynamic microwave photonic filter is demonstrated. ...
Dynamic reconfiguration of a microwave photonic filter by tuning its basic delay based on stimulated Brillouin scattering-induced slow light and optical phase shift of the optical carrier is experimentally implemented. The measurements confirm that the fre ...
In this work, we study how to use a plasmonic dipole antenna as a multifunctional nanodevice for surface-enhanced Raman spectroscopy (SERS), localized surface plasmon resonance (LSPR) -based sensing and optical trapping. An analytical model is implemented ...

In this thesis, we present the development of a tunable Multi-Heterodyne Scanning Near-Field Optical Microscope (MH-SNOM). This instrument has been built and evaluated for the investigation of optical near fields in amplitude, phase and polarization. With ...
Monolayer thin films with ethylene-glycol function onto gold surfaces by using thiols have been extensively investigated. They have been proposed as precursors for applications to bio-detection, where their hydrophilic character improves both specificity a ...
