Product introduction
HC-QN series electro-optic phase modulators use the electro-optic effect of lithium niobate crystal to realize the phase modulation of optical signals, and use titanium diffusion or proton exchange technology to manufacture optical waveguides, which can realize dual-polarization or single-polarization phase modulation. Has that characteristic of low insertion loss, high modulation bandwidth, low half-wave voltage, high damage optical pow and the like, and is mainly applied to the fields of optical chirp control in a high-speed optical communication system, phase delay in a coherent communication system, optical sideband generation, phase modulation in quantum communication, stimulated Brillouin scatter (SBS) reduction in an analog optical fiber communication system and the like.
