We present an approach for rational design and optimization of plasmonic arrays for ultrasensitive surface enhanced infrared absorption (SEIRA) spectroscopy of specific protein analytes. Motivated by our previous work that demonstrated sub-attomole detecti ...
State-of-the-art nanophotonic devices based on semiconductor technology use total internal reflection or the photonic bandgap effect to reduce the waveguide core dimensions down to hundreds of nanometers, ensuring strong optical confinement within the scal ...
The mid-infrared range is of interest in spectroscopic applications, due to the large number of organic compounds that exhibit characteristic absorption bands in this spectral region. Semiconductor technology, however, has been developed mainly for the nea ...
Photonic crystals are stuctures in which the refractive index varies periodically on the wavelength scale in one, two or three dimensions. Due to interference effects, these structures can forbid light propagation over a large spectral range called "the ph ...
We experimentally demonstrate the active inhibition of subwavelength confined cavity modes emission and quality factor enhancement by controlling the cavity optical surrounding. The intrinsic radiation angular spectrum of modes confined in planar photonics ...
Photonic crystals (PhC) are periodically structured electromagnetic media, in which light within some frequency ranges cannot propagate through the structure. Such frequency ranges are commonly referred as photonic band gaps (PBG). The length scale of the ...
We study the reflection of a tightly focused Gaussian beam off a near symmetric resonant tunneling structure comprising two identical coupled waveguides. The coupled waveguides are loaded on each side by a spacer layer and a high index prism. Reflection of ...

We demonstrate a compact multi-resonant metamaterial structure based on integrated U- and T-shaped nano-aperture antennas. We investigate the physical origin of the multi-resonant behavior and determine the parameter dependence of the nano-aperture antenna ...
We present new parametric channelized receiver for instantaneous RF spectrum characterization. Single resonant cavity filter combined with parametric wavelength multicasting achieved simultaneous channelization of 10GHz signal with 1GHz resolution and exti ...
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 ...
