ABSTRACT
The refractive index change induced by depletion of highly doped n-type InGaAsP materials is calculated. A new, numerically simple and accurate model for the high carrier density band-gap shrinkage is introduced. In contrast to the results of earlier calculations, our results show that the refractive index change depends only weakly on the difference between the optical wavelength used and the band-gap wavelength.
