The spectra were spliced in an additive manner38 [p.17], to remove the steps introduced at the junction between the 3 detectors (VNIR, SWIR1, and SWIR2) used to cover the vis-NIR spectral range. The noisiest part of the spectral range was excluded (350–400 nm). The Savitzky-Golay...
Humans perceive a portion of the electromagnetic wave spectrum known as the eponymic “visible light spectrum.” Waves in the visible light spectrum range from ∼400nm (violet) to ∼700nm (red). The biology of the eye, or specifically the retina, which is where the field of light recep...
摘要: Second harmonic generation over the entire visible range inNd3+doped and undopedGd2(MoO4)3crystals under ultrashort hypercontinuum pumping is presented. The continuous tuning ranges from 487 to 790 nm in a single crystal.关键词: materials science gadolinium compounds nonlinear optics molybdates...
In this study, we used visible-near infrared (vis-NIR) spectra to describe topsoils across Denmark. We used 693 agricultural topsoil samples (0-20 cm) from the Danish soil collection and measured them with a vis-NIR spectrometer covering the spectral range between 350 and 2500 nm. We ...
Firstly, the RTP properties of TpPBr as a typical model were discussed in detail. Under different excitation lights from UV of 365 nm to visible of up to 560 nm, the profiles of phosphorescent spectra of TpPBr crystal kept approximately the same. The main emission was in the range of...
We propose an approach for left-handed metamaterial synthesis in the visible frequency range, based on Mie resonance in dielectric/plasmonic rods. On the basis of a qualitative analytical description, the mechanism of plasmonic-particles-based Mie resonance tailoring of the hybrid rod-type resonator ...
Broadband negative refraction (wavelength 270–1300 nm) is numerically demonstrated. Compared to conventional horizontally-stacked multilayer structures, the vertically-stacked multilayer structure has a broader range of working wavelength in the visible range, with higher transmittance. We also report a ...
Here we experimentally demonstrate ultra-thin metasurface holograms that operate in the visible range whose thickness is only 30nm (approximately 1/23 of the operational wavelength). To our knowledge, this is the thinnest hologram that can provide both amplitude and phase modulation in the visible ...
In this paper, we report on our progress on a moderate confinement Si33N44/SiO22 waveguide platform amenable for biophotonics, tele/datacom and sensing applications from the VIS to the long NIR (400–3700 nm wavelength range). The paper is structured as follows. Section 2 summarizes the prese...
