Paper Abstract

The BSO crystal must be described as an elliptical birefringent. Under the photo-induced modulation of an applied electric-field, the analysis of its polarization effect can be usefully splitted into successive operators, defined as a rotatory power followed with a linear birefringence, providing that proper values are determined for these equivalent operators, which are not identical to the intrinsic optical activity and birefringence of the crystal. A theoretical analysis of this elliptical birefringence is presented, together with experimental results. One shows that the definition of the half-wave voltage, usually considered as a characteristic, does not apply correctly to optically active crystals. Correction terms are calculated and a new method is also implemented, to determine the electro-optic coefficient. The results are given for the BSO crystal in the full visible range. These results are shown to allow a computer simulation of the performances, which enables to choose the optimal geometry of the crystal for any specific application.
