TuA1.1 - OBSERVATION OF EXCEPTIONAL-POINTS IN PLASMONICS
Abstract
Abstract
We report using an original approach, the first observation of exceptional point in plasmonic at room temperature.
TuA1.2 - MULTISPECTRAL PLASMONIC PERFECT ABSORBERS INTEGRATED WITH ROOM-TEMPERATURE VOX AIR-BRIDGE BOLOMETERS
Abstract
Abstract
Room-temperature microbolometer arrays with sensitivity in narrow wavelength bands for spectral imaging in the mid-wave and long-wave infrared are described. The approach is based on vanadium-oxide air-bridge bolometers that are integrated with plasmonic resonant absorbers to maintain response speed without adding processing complexity.
TuA1.3 - PLASMONIC INFRARED ATTENUATOR
Abstract
Abstract
A variable attenuator for high-powered IR beams, based on MEMS-controlled excitation of surface plasmon polaritons on suitably conducting surfaces is described. Materials choice determines the useful spectral band. Intensity variation over nine-orders is theoretically possible.
TuA1.4 - ENHANCED MWIR LED PERFORMANCE WITH A PLASMONIC GRATING
Abstract
Abstract
To improve the efficiency of GaSb-based mid-wave infrared LEDs, we investigated the enhanced spontaneous emission by a dipole in a thin slab numerically. A Purcell factor around 30 was achieved by combining a thin waveguide and plasmonic grating.
TuA1.5 - MICROSPHERE PHOTOLITHOGRAPHY PATTERNING OF PLASMONIC SENSORS ON OPTICAL FIBER
Abstract
Abstract
Microsphere Photolithography uses a self-assembled hexagonal lattice of microspheres as an optical element to focus collimated light to an array of photonic jets inside a layer of photoresist. This technique is applied to pattern optical fiber for refractive index sensing and Surface Enhanced Raman Spectroscopy.
