Description
LiNbO3 crystal has been widely used in optical waveguide and optical communication technology because of its excellent electro-optical properties. It is an ideal substrate material for many integrated optoelectronic devices. Because of the large electro-optic coefficient of LiNbO3, the half-wave voltage is low. The electro-optic effect of LiNbO3 crystal is usually used to modulate the optical signal. Electro-optic modulation is divided into longitudinal and transverse, and LiNbO3 is mainly used in transverse modulation. It has been widely used in medium and low power solid-state lasers.
