Strong optical nonlinearity of the nonstoichiometric silicon carbide …

The nonlinear refractive index increases to 1 ± 0.1 × 10 −11 cm 2 W −1 upon increasing the C/Si composition ratio up to 1.83, which is four orders of magnitude higher than that of bulk SiC. The increased C/Si composition ratio reduces the lattice constant and the effective mass of the Si x C 1− x film and enhances its nonlinear refractive index effectively.

List of refractive indices - Wikipedia

List of refractive indices. Many materials have a well-characterized refractive index, but these indexes often depend strongly upon the frequency of light, causing optical dispersion. Standard refractive index measurements are taken at the "yellow doublet" sodium D line, with a wavelength of 589 nanometers . There are also weaker dependencies

19/6/2019· The refractive index of different possible existing structures in these films have been collected from literature and shown in table 2. According to this table, the low refractive index of VP1 might be due to the high carbon incorporation in the form of amorphous carbon in the film structure in spite of high Si-C bond density compared to the other films in this set of samples.

The refractive index of each of the four common silicon carbide polytypes has been measured over the visible range. The data were analyzed in an attempt to relate the birefringence to the relative hexagonal character of the polytype. A general relationship exists, namely, that the birefringence increases with increasing hexagonal character of the polytype. This relationship is not sufficiently
