Abstract :
The bond-charge model of Jha and Bloembergen has been extended to ordered, pseudodiamond GexSi1-x/Si super-lattices to calculate the Pockels coefficient and the second-order susceptibility of these structures. We find that the Pockels coefficient is approximately 1 Ã 10-12 m/V over the near-infra-red range.
