Multi-functional Integrated Optical Device
The multi-functional integrated optical device is made by lithium niobate annealing-proton exchange process, and has the functions of light splitting, phase modulation, polarizing, etc. It is mainly applicable to fiber optic gyroscopes, fiber optic sensors and other fields, and has been applied in batches in multiple national key projects due to its stable and reliable product performance.
  • Low insertion loss and half-wave voltage
  • Low back light reflection and residual strength modulation
  • High batch consistency and long-term stability
