Single crystals with the Sillenite structure, Bi₁₂MO₂₀ (M=Si, Ge, Ti) have a fortunate combination of electrooptic, acoustooptic and piezoelectric properties and are thus promising materials for optoelectronics.

The fabrication of sillenite oxide thin-film structures by different techniques permits the development of a long list of devices, including integrated-optics devices.

The strong spectral dependence of the photoconductive properties of these crystals and their electrooptic properties makes it possible to develop a wide variety of devices including spatial light modulators, hologram recording devices, phase conjugation, photorefractive incoherent-to-coherent optical converters.

The relatively large electrooptic effect of sillenite oxide makes them useful also for optical fiber electric field sensors with high thermostability.

Available sizes for polished elements are (3 - 20) x (3 - 20) x (3 - 20) mm³.
Other single crystals with Sillenite structure such as Bi₁₂TiO₂₀ (BTO) and doped Bi₁₂SiO₂₀ (BSO), Bi₁₂GeO₂₀ (BGO) are also available.
