If using a single atom to capture high-resolution images of nanoscale material sounds like science fiction, think again.That’s exactly what the Quantum Sensing and Imaging Group at UC Santa Barbara ha...
Evaluation of ultraviolet, visible, and near infrared spectroscopy for the analysis of wine compounds
spectral analysis glycerol chemometrics PLS PCR organic acids ethanol
2014/3/28
Spectroscopy of UV-VIS-NIR combined with chemometric analyses was used as a non-destructive technique to build models for the quantitative characterisation of the main compounds of wine. The work in m...
High Q micro-ring resonators fabricated from polycrystalline aluminum nitride films for near infrared and visible photonics
High Q micro-ring resonators polycrystalline aluminum nitride films visible photonics Optics
2012/5/29
We demonstrate wideband integrated photonic circuits in sputter-deposited aluminum nitride (AlN) thin films. At both near-infrared and visible wavelengths, we achieve low propagation loss in integrate...
Experimental demonstration of a broadband array of invisibility cloaks in the visible frequency range
Experimental demonstration broadband array invisibility cloaks visible frequency range Optics
2012/4/20
Very recently Farhat et al. [1] have suggested that arrays of invisibility cloaks may find important applications in low-interference communication, noninvasive probing, sensing and communication netw...
Electric dipole-free interaction of visible light with silver metadimers
Electric dipole-free interaction visible light silver metadimers Optics
2012/4/19
In subwavelength-sized particles, light-induced multipole moments of orders higher than the electric dipole are usually negligibly small, which allows for the light-matter interaction to be accurately...
Development of Rapid Assessment Method to Determine Bacterial Viability Based on Ultraviolet and Visible (UV-Vis) Spectroscopy Analysis Including Application to Bioaerosols
Bacterial viability Ultraviolet and visible spectroscopy Optical density Bioaerosols
2016/3/25
We evaluated a method for the assessment of bacterial viability that is based on ultraviolet and visible (UV-Vis)
spectroscopy analysis. The quantities of intracellular materials inside a cell vary d...
A copper negative index metamaterial in the visible / near-infrared
copper negative index visible near-infrared Optics
2011/8/11
Abstract: We propose a design for a novel plasmonic copper metamaterial with an index of refraction equal to -1 at an operating wavelength of 700 nm. Using numerical simulations, we demonstrate negati...
Are scalar mesons visible in B+- --> pi+pi-pi+- decays?
scalar mesons visible B+- --> pi+pi-pi+- decays
2011/1/5
Two pion effective mass and helicity angle distributions in the charged B-meson decays into three charged pions are studied. The weak decay amplitudes are calculated in the framework of the QCD factor...
Physicists in California have observed true quantum behaviour in a macroscopic object big enough to be seen with the naked eye. This is the first time this feat has been achieved and it could shed lig...
The optical properties in Visible-light Excited Phosphor Sheet (VEPS) system were discussed and calculated. Different to the conventional LED backlight with white LEDs, VEPS system applies blue LED ch...
