1550nm Lithium Niobate High-Frequency Phase Modulator (40GHz Electro-Optic Bandwidth)

The 1310/1550nm lithium niobate (LiNbO3) high-frequency phase modulator uses titanium diffusion or proton exchange processes to create optical waveguides. The input and output optical fibers are precisely obliquely coupled with the waveguides, utilizing the electro-optic effect of the lithium niobate material to achieve phase modulation of optical signals. The titanium diffusion (Ti-indiffusion) or proton exchange (APE) waveguide process can respectively achieve birefringence or single polarization phase modulation

Product features：Low Insertion Loss、 Low Drive Voltage、 Titanium Diffusion or Proton Exchange Waveguide、 Excellent Long-Term Stability

Application area：Fiber Optic Communication、 Microwave Photonics、 Quantum Communication、 Optical Sensing、 Optical Chirp
