Abstract
A simulation model is for an optical modulator that may include an optical phase shifter in a semiconductor material structure between two sections of an optical waveguide. The semiconductor material structure may include one of a P-N and P-I-N junction in a plane parallel to an axis of the optical waveguide. The model may include a diode configured to characterize an electrical behavior of the one of the P-N and P-I-N junction such that a change in a global refractive index of the optical phase shifter is expressed, by a coefficient, based upon an amount of charges in the one of the P-N and P-I-N junctions and raised to a power. The coefficient and the power may be empirical values based upon the semiconductor material and a wavelength.
