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.
