Optical properties

The Sellmeier equation that describes how the optical refractive index for indium phosphide depends on wavelength is given by $n^2(\lambda) = 7.255+ \frac{2.316 \lambda^2 }{ \lambda^2 - 0.6263^2}+ \frac{2.765 \lambda^2 }{ \lambda^2 - 32.935^2},$ where λ is the wavelength in micrometres. In Optics, the Sellmeier equation is an Empirical relationship between Refractive index n and Wavelength λ for a The refractive index (or index of Refraction) of a medium is a measure for how much the speed of light (or other waves such as sound waves is reduced inside the medium In Physics wavelength is the distance between repeating units of a propagating Wave of a given Frequency. A micrometre ( American spelling: micrometer; symbol µm) is one millionth of a Metre, or equivalently one thousandth of a Millimetre

This gives refractive index values rising from around 3. 21 at 10 µm and 3. 32 at 1. 5 µm to 3. 47 at 1. 0 µm.
