Author

Basséras, P., Gracewski, S. M., Wicks, G. W., and Miller, R. J. D.

Subjects
*GALLIUM arsenide, *ALUMINUM, *REFLECTANCE
Abstract

Discusses a study on the optical generation of life-frequency acoustics in periodic multilayer structures made of alternating layers of gallium arsenide and aluminum-gallium arsenide. Experimental technique; Calculation of acoustic modes dispersion relation; Details of the strain-induced change in reflectivity.

3. Theoretical analysis of acoustic transients in lithium niobate electro-optic modulators.

Author

Basséras, P., Miller, R. J. Dwayne, and Gracewski, S. M.

Subjects
*ELECTRIC transients, *DOUBLE refraction, *ELECTRONIC excitation
Abstract

Investigates the acoustic transients generated by high-voltage pulses in an excited LiNbO[sub3] Pockels cell. Expressions of the strain fields and the strain-induced change in index of refraction; Importance of using short-pulse excitations for minimizing the strain-induced birefringence effects for laser-beam geometries; Effects of acoustic waves on the laser-light polarization.
