Gaas refraction
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 … WebRefractive index n versus photon energy for a high-purity GaAs. ( no ~5·10 13 cm -3 ). Solid curve is deduced from two-beam reflectance measurements at 279 K. Dark circles are obtained from refraction …

Webdimensions of the waveguide and the refractive indices of undoped bulk layers are known to a very good accuracy. The results of the calculations together with the refractive indices of the undoped epitaxial layers are given in Table 1. Calculated effective indices, nph. determine the phase velocity and are about 1% lower than that of the GaAs core.
