Abstract

The relationship between the three main one electron mechanisms that lead to an intensity dependence of the refractive index of a semiconductor namely the band filling effect, virtual interband transitions and the motion of free carriers in a nonparabolic band, is investigated theoretically. The semiconductor is modelled as an ensemble of independent two level electron systems and its nonlinear response to a light pulse is evaluated algebraically. In particular, it is shown (i) how the dependence of the dephasing time on optical frequency allows a smooth transition from the band filling regime to the virtual transitions regime and (ii) how the nonlinear motion of free carriers in a nonparabolic band is related to the nonresonant optical Stark effect.
