Lithium Niobate Crystal (LiNbO3)


LiNbO3 is one of the most attractive materials for optoelectronics. A great variety of devices has been developed based upon this material having unique electro-optical, photoelastic, piezo-electric and non-linear properties combined with good mechanical and chemical stability and wide transparency range.

Del Mar Ventures offers a lot of products made of high quality LiNbO3 crystals of both Acoustical and Optical grades. Typically, Czochralsky grown and poled along Z-axis boules are used with sizes up to 80 nm in dia. and 100 mm in length.

Other boules orientations can be applied for some purposes (SAW substrates, piezotransducers).

Optical damage effect which exhibits in congruent melt grown LiNbO3 certainly limits it’s applications in high power non-linear and E-O devices. For this purpose specially grown LiNbO3 can be offered which has composition near stoichiometric similar to the Li-rich VTE LiNbO3 with the obvious advantage that bulk samples can be obtained.

Custom growth of some related materials is available.

For example: Fe:LiNbO3 - photorefractive material for optical memory devices,
Ba2LiN5O15 (BLN) - analog of BANAN crystal for E-O modulators
and non-linear applications.
