Passive photonic chips are essential components in applications like fiber optic gyroscopes and optical communications where signal processing and light manipulation are required without external power. These chips, often made from lithium niobate, feature integrated waveguides for functions such as light splitting and polarization handling, with PM fiber pigtail interfaces for enhanced signal integrity. Suppliers such as Shanghai Aoshi Control Technology Co.Ltd provide a range of these components, ensuring compatibility with various fiber sensing applications.
