In this paper, we present an extension of the modified single oscillator model able to predict the temperature related variations of refractive index of InP/InGaAsP materials. Model is based on three parameters- oscillation energy, dispersion energy and bandgap energy. The proposed model enables to calculate the thermo-optic coefficient in the typical telecommunication wavelength range. The obtained numerical results are compared with experimental data and found in good agreement.

Abstract
In this paper, we present an extension of the modified single oscillator model able to predict the temperature related variations of refractive index of InP/InGaAsP materials. Model is based on three parameters- oscillation energy, dispersion energy and bandgap energy. The proposed model enables to calculate the thermo-optic coefficient in the typical telecommunication wavelength range. The obtained numerical results are compared with experimental data and found in good agreement.File in questo prodotto:
