Used extensively in optical modulators for telecommunications due to its excellent electro-optic properties, enabling high-speed data transmission in fiber-optic networks. Also employed in surface acoustic wave (SAW) devices for mobile phones and signal processing equipment because of its piezoelectric characteristics. Commonly found in nonlinear optical applications such as frequency doubling to convert laser light to different wavelengths. Utilized in photonic integrated circuits and waveguides for integrated optics and quantum computing research. Serves as a key material in sensors, acousto-optic deflectors, and tunable filters.
