Gaas refraction
WebApr 26, 2024 · The dielectric rods are made of GaAs which has less switching power for nonlinear application than silicon. At the wavelength of the structure, the GaAs refractive index is lower than the Si refractive index by 1.542 μm, which makes the light waves propagate in the GaAs at a higher speed. WebThe refractive index of GaAs has been measured in the wavelength range from 0.97 to 17 mum, which covers nearly the entire transmission range of the material.

WebNov 1, 2024 · For this purpose, the refractive indices of GaAs and InAsBi were measured using spectroscopic ellipsometry. The complex Sellmeier coefficients were then obtained by a least-square fitting procedure. WebInAs quantum dots have been used to extend the absorption edge of InGaAs/GaAs quantum well solar cells from 940 to 1100 nm. In order to improve absorption of infrared radiation by the thin 300 nm active layer, we exploit its high refractive index, which acts as a waveguide for certain frequencies of light.

WebFabry–Perot cavities were used to obtain experimental values for the quantity (n−λ dn/dλ) near the absorption edge in GaAs at 2 K. Here n is the refractive index and λ is the wavelength of light. Using an adjusted Sellmeier‐type equation, n and −dn/dλ were calculated as a function of wavelength at 2 K. These are the only available values of n … WebMay 8, 2000 · The refractive index of GaAs, as measured by the prism refraction method, is reported here for photon energies from 0.7 eV up to the absorption limit set …
