Exail header erbium doped fibers

DPSK demodulator (MINT)

Delay Line Interferometers


Exail’s Delay Line Interferometers (DLI) enhance your signal quality!

DLIs performs the interference between an incoming signal and itself delayed by one bit-time, allowing phase-keyed to amplitude-keyed signal conversion.

Our DLIs feature the widest tunable Free-Spectral Range (FSR) range available. They can have a fixed, but tunable by design, FSR (MINT product line) or can have an adjustable FSR (WT-MINT product line) thanks to a patented motorized technology

Features

Benefits

    • High extinction ratio for a highly contrasted interference pattern
    • Sensitive and accurate detection based on phase to amplitude conversion
    • High level of customization (adjustable or fixed FSR, wavelength range, wide range of possible interface fibers…)
      • 2 options available:
        • U for Ultrafast phase tuning using a piezoelectric
        • L for Low voltage phase tuning using a thermisto

Applications

  • Quantum Communications (DV-QKD)
  • D(Q)PSK demodulation
  • Sensing (Distributed sensing, Reflectometry, etc)
