High sensitive read write holographic memory BGO piezoelectric crystal substrate
Bismuth germanate (Bi12GeO20) has high electro-optic coefficients (3.3 pm/V for Bi12GeO20) making it useful in nonlinear optics for building Pockels cells, and can also be used forphotorefractive devices for ultraviolet range. The Bi12GeO20 crystals are piezoelectric, show strong electro-optical and acousto-optical effects, and find limited use in the field of crystal oscillators and SAW devices. Single crystal rods and fibers can be grown by floating zone process from a rod of mixture of bismuth oxide and germanium oxide.The crystals are transparent and brown colored.
