Abstract

Electro-optic effects in single crystals of 2-cyclooctylamino-5-mitropyridine and 2-(N- prolinol)-5-nitropyridine have been investigated. The measured wavelength dependence of the electro-optic coefficients can be well explained with the quantum-mechanical two-level model. Enhancements of these coefficients near acoustic phonon resonances of up to a factor of 25 were observed when scanning the modulation frequency of the applied electric field. A comparison between measured second-order polarizabilities and electro-optic coefficients revealed that optic phonons may still contribute considerably to the electro-optic effects in the investigated molecular crystals. A simple expression to estimate the limiting values of electro- optic coefficients is proposed and compared with values of known molecular crystals.
