Photonic chips designed for waveguide functions are essential components in applications such as fiber optic gyroscopes, fiber sensing, and optical communications. These products primarily utilize a lithium niobate (LiNbO₃) material platform and feature passive polarization-maintaining (PM) fiber pigtail interfaces. Suppliers like Shanghai Aoshi Control Technology Co.Ltd offer a range of these integrated optical chips. On FindLight, buyers can compare specifications, request pricing, and connect directly with manufacturers without needing to register.
