1310nm LiNbO3 Phase Modulator

 

Description

LiNbO₃ phase modulator, made with the proton exchange or Tiindiffusion method. It features low insertion loss, low drive voltage, low back reflection, wide wavelength range, and high efficiency. It is ideal for optical chirp control in high speed fiber communication systems, high-speed phase control for sensor systems, phase shift key modulation for coherent communication systems, optical frequency shifting for measurement systems, and stimulated Brillouin scattering (SBS) reduction for analog fiber optic systems.

Features
● Low Insertion Loss
● Low Drive Voltage
● Small Package
● Long life and High realibility

Applications
● Fiber sensor application
● Coherent optical communication field
● Quantum secure communication
