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.

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.

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.

Abstract

Abstract

We report our recent work on utilizing nonlinear optical microscopy techniques to obtain diffraction-limited, large area, spatially resolved, multi-spectral images of 2D materials and resonant metasurfaces. Thickness dependence of harmonic generation from multi-layer Tin diselenide and spatially-dependent saturation effects in silicon nanodisk arrays are discussed.
