Multicore Fiber

  • Simultaneous transmission of different signals down different cores
  • Photosensitive core designs for FBG inscription
  • Custom designs possible - more cores, mismatched cores, different core positions

Typical Applications:

  • Temperature and strain sensors
  • Structural Health Monitoring (SHM)
  • Active Optical Cables (AOC)
  • Space Division Multiplexing (SDM) transmission cables
  • Silicon photonics
  • Quantum Key Distribution (QKD) (non-spun)
