Multicore Fiber
Multicore fibers provide a platform for the next generation telecommunication devices and sensor systems.
- 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)
