PLC Mach-Zehnder Interferometer

product imageStable and reliable Mach-Zehnder interferometer based on silica-based planar lightwave circuit. It is suitable solution for the high-speed DPSK/DQPSK transmission systems.


  • Fast optical frequency tracking by thermo-optic effect
  • Low PDf (Polarization Dependent Frequency shift)
  • Stable against mechanical vibration
  • High reliability


  • DPSK/DQPSK demodulation
  • Time-domain optical pulse multiplexing
