Query: Modeling of strain-induced Pockels effect in Silicon   We propose a theoretical model to describe the strain-induced linear
electro-optic (Pockels) effect in centro-symmetric crystals. The general
formulation is presented and the specific case of the strained silicon is
investigated in detail because of its attractive properties for integrated
optics. The outcome of this analysis is a linear relation between the second
order susceptibility tensor and the strain gradient tensor, depending
generically on fifteen coefficients. The proposed model greatly simplifies the
description of the electro-optic effect in strained silicon waveguides,
providing a powerful and effective tool for design and optimization of optical
devices.
