1.7 Electrooptic Properties
1.7.1 Linear Electrooptic Coefficients
The linear electrooptic effect occurs in acentric crystals. Only 21 acentric groups (those lacking a center of inversion) may have nonvanishing coefficients. Reduced electrooptic matrix forms are given in the two references below.
If the electrooptic coefficient rij is determined at constant strain (by making the measurement at high frequencies well above acoustic resonances of the sample) the crystal is clamped, as indicated by S. If the rij is determined at constant stress (at low frequencies well below the acoustic resonances of the sample) the sample is free, as indicated by T. The electrooptic coefficients are generally those for room temperature. Typical accuracies for rij are ±15%. Unless shown explicitly, the signs of rij have not been determined. As a rule, rij has little optical wavelength dependence in the transparent region of the crystal.
The following tables were adapted from:
Kaminow, I. P., Linear Electrooptic Materials, Handbook of Laser Science and Technology, Vol. IV (CRC Press, Boca Raton, FL, 1986), p. 253.
Holland, W. R. and Kaminow, I. P., Linear Electrooptic Materials, Handbook of Laser Science and Technology, Suppl. 2 (CRC Press, Boca Raton, FL, 1995), p. 133.
A comprehensive table of electrooptic constants including extensive data on refractive indices and curves of wavelength and temperature dependence of electrooptic coefficients is given in Cook, W. R., Hearmon, R. F. S., Jaffe, H., and Nelson, D. F., Piezooptic and electrooptic coefficient constants, Landolt-Börstein, Group III, Vol. 11, Hellewege, K.-H. and Hellewege, A. M., Eds. (Springer-Verlag, New York, 1979), p. 495.
The following tables are divided according to the general structure of the electrooptic materials, i.e., tetrahedally coordinated binary AB compounds that are semiconductors, ABO3-type compounds that are ferroelectric or pyroelectric, isomorphs of ferroelectric KH2PO4 and antiferroelectric NH4H2PO4, other compounds that do not fit the previous categories, and organic compounds. Although nonlinear optic coefficients have been measured for many organic crystal and can be converted to equivalent electrooptic coefficients, only direct phase retardation measurements of the electrooptic effect are included in the last table.
