Plasmonic nanocrystals were attracting a lot of attention both for fundamental studies and different applications, from sensing to imaging and optoelectronic devices. Transparent conductive oxides represent an interesting class of plasmonic materials in ad ...
The main topic of this thesis is the fabrication and characterization of structures smaller than the wavelength of light, for operation in the visible or near infrared spectral range. In the first part of this thesis, the fabrication of periodic structures ...
There has been a very strong development of the sensors based on surface plasmon resonance during the last thirty years, mostly for biological and biomedical applications. If the first experiments in this field were carried out at the beginning of the 20t ...
We use a simple modification to a conventional SLR camera to capture images of several hundred scenes in colour (RGB) and near-infrared (NIR). We show that the addition of near-infrared information leads to significantly improved performance in a scene-rec ...

Wavelength tunable emitters and detectors in the mid-IR wavelength region allow applications including thermal imaging and gas spectroscopy. One way to realize such tunable devices is by using a resonant cavity. By mechanically changing the cavity length w ...
Successful applications of nanoparticles are often limited by insufficient nanoparticle stability due to low binding affinity of dispersants. However, excellent Fe3O4 nanoparticle stability was reported in a recent study (Nano Lett. 2009, 9, 4042 -4048) th ...
We report a prototype CO2 gas sensor based on a simple blackbody infrared source and a spectrally narrow quantum cascade detector (QCD). The detector absorption spectrum is centered at 2260 cm−1 (4.4 μm) and has a full width at half maximum of 200 cm−1 (25 ...
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 ...
We present a description of sum frequency scattering experiments to probe the interfacial vibrational spectrum of nanoscopic oil droplets dispersed in water. SF scattering measurements as a function of optical path length, infrared (IR) pulse energy and pa ...
A review. Many properties of single-walled carbon nanotubes (SWCNTs) make them ideal candidates for sensors, particularly for biol. systems. Both their fluorescence in the near-IR range of 820-1600 nm, where absorption by biol. tissues is often minimal, an ...
