摘要：

A theoretical k*p model for the linear electro-optic (LEO) spectrum near the E-1/E-1+Delta(1) energies is presented. The calculated spectrum reproduces the important features of the experimental ones. In particular, it explains the observed energy shifts of the resonance near the E-1/E-1+Delta(1) energies, and the predicted LEO coefficient agrees well with the experimental one. The predicted linewidth, on the other hand, is about twice that of the observed one. The LEO strength is found to be dominated by the excitons. This is qualitatively consistent with the observed large change of LEO strength with temperature. (C) 1998 American Institute of Physics.
