Optical Grade LiTaO3 Wafer

Description

Optical grade Lithium Tantalate (LiTaO3) wafers are high-quality, single-crystal wafers that are specifically designed for use in advanced optical applications. These wafers are carefully grown and processed to ensure a high degree of purity, uniformity, and flatness, which are essential for achieving precise optical performance.

Optical grade LiTaO3 wafers are typically grown using the Czochralski method, which involves melting a high-purity LiTaO3 crystal and slowly pulling it from the melt to form a single-crystal ingot. The ingot is then sliced into thin wafers, which are polished to a high degree of flatness and surface quality.

The properties of optical grade LiTaO3 wafers make them ideal for a variety of optical applications, including frequency converters, modulators, and acousto-optic devices. They have a high refractive index, low optical loss, and a high electro-optic coefficient, which makes them highly sensitive to electrical fields and useful for modulation of optical signals.

In addition to their optical properties, LiTaO3 wafers have excellent piezoelectric properties, which makes them useful in acoustic wave devices, such as filters and resonators. They are also used in surface acoustic wave devices (SAW) for telecommunications and sensing applications.
