Ferroelectric Tungsten Bronze Bulk Crystals and Epitaxial Thin Films for Electro-Optic Device Applications
Abstract
One -3 cm diameter single crystals of the bronze compositions SBN:50 and SBN:60 have been successively grown. Optical striations in SBN:60 are found to arise from impurities and temperature instability during growth. Improvements in temperature stability, rotation rate, and post-annealing conditions have improved the optical quality considerably. LPE growth of SBN:48 on SBN:60 and SBN:50 single crystal substrates has been successful, with crystal films of 10- 15 micrometers in thickness grown. Piezoelectric and electro-optic measurements have been performed on PBN and SBN single crystals. Electro-optic g and r coefficients are shown to be easily determined from measurements of the birefringence delta n31. The linear coefficients are particularly promising for both PBN and SBN.
