Abstract We report the emission of strong coherent broadband terahertz radiation from 6H-Silicon-Carbide (SiC) excited with optical pulses. The measured terahertz spectral signal-to-noise ratio is better than one thousand. We determine that the terahertz radiation is
Birefringence is the optical property of a material having a refractive index that depends on the polarization and propagation direction of light.[1] These optically anisotropic materials are said to be birefringent (or birefractive). The birefringence is often quantified as the maximum difference between refractive indices exhibited by the

Silicon carbide and silicon carbon nitride thin films were grown by pulsed laser ablation of SiC targets in vacuum or in the presence of a controlled N 2 atmosphere. The influence of the substrate temperature and of the N 2 partial pressure on the optical and structural properties of the samples were investigated by means of Fourier transform infrared (FTIR), Raman, X-ray photoelectron and

Index of Refraction: fixed and variable ratio at given wavelength Different presentation approaches: (A) lists all refractive index values (n or k) along a range of wavelengths and (B) gives individual refractive index values, along with more information ranging from bandgaps, to temperature dependencies, to fabriion information, depending on the material.
In this study, hydrogenated amorphous silicon carbide thin films were deposited by reactive ion-beam sputtering under varying conditions to determine whether a film''s optical properties can be controlled, focusing on refractive index. Using a Kaufman type ion source to sputter a pure silicon target, three distinct series of films were grown. The first series varied the mixture of methane and

Silicon carbide develops in the furnace as a solid cylindrical ingot around the graphite core, with concentric layers that decrease their SiC content with the distance from the core. It can be black or green depending on the composition of the raw materials used.
Rectangular Brewster windows are uncoated substrates used in an optical system at Brewster’s Angle, the angle at which p reflectance drops to zero. This can be calculated from: ΘB = tan-1(n) where ΘB is Brewster’s Angle and n is the material’s index of refraction.
Silicon Carbide Conductive Wafers Product Description: Due to Silicon Carbide (SiC) physical and electronic properties, SiC based devices are well suitable for short wavelength optoelectronic, high temperature, radiation resistant, and high-power/high-frequency electronic devices, compared with Si and GaAs based devices.
Made by Schott, this glass has good homogeneity in terms of refractive index throughout its surface, and as a block glass it comes in a variety of forms. N-BK7 is a softer glass that is significantly more sensitive to thermal variations than either fused quartz or low CTE materials such as Zerodur so special considerations have to be made in manufacturing to adjust for these properties.
Moissanite is a mineral that was first discovered in fragments of the meteorite at Diablo Canyon or Meteor Crater in Arizona. It was named in honor of its discoverer, Nobel Prize winner Dr. Ferdinand Henri Moissan. Synthetic moissanite is also known as silicon carbide after its chemistry and by the trade name, carborundum..
This mineral consists of silicon carbide. As the naturally occurring quantity of Moissanite is so rare, the wish to produce silicon carbide as Moissanite in an artificial way was born. In 1997, Moissanite was produced artificially for the first time in gemstone quality.
