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.
TuC1.4 - LONG-WAVE INFRARED VARIABLE EMISSIVITY COMBAT IDENTIFICATION PANEL
Abstract
Abstract
A structured thin film with widely variable long-wave emissivity and insignificant change to its visible reflectance is proposed and demonstrated theoretically. An application is dynamic Identification Friend or Foe (IFF) panel viewable at LWIR but optically invisible.
WD4.4 - OPTICAL LIMITER USING EPSILON-NEAR-ZERO GRATING
Abstract
Abstract
Fast optical limiters are needed to protect sensors from intense short laser pulses. An optical limiter design based on a conducting-oxide grating with a large nonlinear refractive index at the plasma frequency is proposed and investigated.
