Spectral analysis of strongly enhanced visible light transmission through single C-shaped nanoapertures
We designed, fabricated, and characterized single C-shaped apertures in an Au film, resonant in the visible regime. Our C-shaped apertures showed transmission enhancement of 13–22 times over a squareExpand

ENTROPIC ATTRACTION AND REPULSION IN BINARY COLLOIDS PROBED WITH A LINE OPTICAL TWEEZER
The long-range entropic forces that arise between two micrometer-sized colloidal spheres in a fluid of much smaller colloidal spheres were directly measured using a line-scanned optical tweezer. ThisExpand

C-shaped nanoaperture-enhanced germanium photodetector.
We present a C-shaped nanoaperture-enhanced Ge photodetector that shows 2-5 times the photocurrent enhancement over that from a square aperture of the same area at 1310 nm wavelength. We demonstrateExpand

Electromagnetic phenomena in advanced photomasks
The adoption of resolution enhancement techniques (RET) for subwavelength lithography relies on performing accurate simulation of mask effects. Although topography effects have been successfully usedExpand

Fractal extensions of near-field aperture shapes for enhanced transmission and resolution.
Families of fractals are investigated as near-field aperture shapes. They are shown to have multiple transmission resonances associated with their multiple length scales. The higher iterationsExpand

A C-shaped nanoaperture vertical-cavity surface-emitting laser for high-density near-field optical data storage
We designed and demonstrated a unique C-shaped nanoaperture (C-aperture) Vertical-Cavity Surface-Emitting Laser with an estimated maximum net power of 113 μW coming from a 70nm C-aperture. SimulationExpand

High-intensity C-shaped nanoaperture vertical-cavity surface-emitting laser with controlled polarization
The authors designed and demonstrated a C-shaped nanoaperture (C aperture) vertical-cavity surface-emitting laser (VCSEL) with a maximum far-field power of 157μW coming from a 70nm C aperture.Expand

C-shaped Nano-Aperture-Enhanced Germanium Photodetector
We present a C-shaped nano-aperture-enhanced Ge photodetector that shows 2~5 times photocurrent enhancement over that from a square aperture of the same area at 1310 nm. We demonstrate theExpand

Telepresence and telerobotics
The capability for a single operator to simultaneously control complex remote multi degree of freedom robotic arms and associated dextrous end effectors is being developed. An optimal solution withinExpand
