Description
The KY-PM series electro-optic phase modulator utilizes the electro-optical effect of lithium niobate to achieve phase modulation of optical signals, and uses titanium diffusion or proton exchange process to fabricate optical waveguides, which can achieve dual-polarization or single-polarization phase modulation. It has low insertion loss, high modulation bandwidth, low half-wave voltage, high damage optical power, etc.This product is mainly used for optical chirp control in high-speed optical communication systems, phase delay in coherent communication systems, the generation of optical sidebands, phase modulation in quantum communication, reducing stimulated Brillouin scattering (SBS) in analog optical fiber communication systems and other fields.
