The ‘QuanTools’ approach begins knowledge driven as it requires first to set the wavelength range of the interest, identify and correct bad/noisy bands, if presented in the data, and define the desire number of absorption features. The second (classification) part is data driven because the ...
There are no actual boundaries between one range of wavelengths and another, because nature did not present us with sharp edges. The number associated with a given name for the waves are only approximate and, of course, so are the names we give to the different ranges. 莴苣斋注:Light, ...
contact pad connected to an array of electrically conductive Au stripes, which serve as nanoantennas that support plasmon resonances in the Vis-NIR regime. For a fixed period (P) of 230 nm, specifically chosen to suppress diffraction orders in the wavelength (λ) range of interest, the spect...
Gain and wavelength dependence of the noise-figure in fiber optical parametric amplification We measure, for the first time, the wavelength resolved electrical noise figure (NF) of a fiber-optical parametric amplifier and find excellent agreement w... P Kylemark,M Karlsson,Peter A. Andrekson - ...
The broad wavelength range of infrared radiation, and the few transparent optical materials available, require that infrared instruments be designed with reflecting optics: radiation is focused with front-surface aluminized mirrors rather than lenses. Because of strong infrared absorption by water vapor an...

we have seen a similar trend in silicon photonics process development. Besides p/n dopants for high-speed modulation, two materials that are now natively supported by several foundries are (1) Ge high-speed photodetectors43, and (2) SiN to expand the wavelength range, enable higher optical pow...
aAt present, there is growing interest in the area of multiplexed interferometric sensors.' The primary objective of this research effort is to develop techniques that allow multiple-sensor networks or arrays to be remotely interrogated and demodulated by using a minimal number of connecting fibers. ...
However, these methods face limitations in full-color displays caused by the wavelength-dependent nature of diffraction. Hence, the color gamut, which represents the range of colors that a device or system can display, is restricted by the inherent wavelength selectivity in the WG displays that ...
of 0.4–0.5% were used in LaBO3, LaPO4, NaLuF4, NaYF4, and NaLaF4, while this required even lower dopant concentrations of 0.1% and 0.05% for Y2O2S and Y2O3, respectively. The vertical lines mark the wavelength range of the5D1\(\to\)7F0–3emissions ofβ-NaREF4:Eu3+and the5...
