Optical Delay Lines

Key Features

  • Low loss
  • Sub-picosecond resolution
  • Wide wavelength range
  • Over 300 psec delay range
  • Polarization insensitive
  • Singlemode and polarization maintaining fiber versions
  • Electrically controlled versions available
  • New miniature style version


Fiber Optic Delay Lines (ODL) consist of an input and output fiber collimator to project the light into free space and collect it again into a fiber. The distance the light travels in free space is precisely controlled, either by controlling the separation between the input and output optics, or by reflecting the light off a movable reflector. In either case, by varying the distance the light travels, one can control the delay time through the device. Delay lines are offered using singlemode, multimode or Polarization Maintaining (PM) fibers.

In general, OZ Optics uses polarization maintaining fibers based on the PANDA fiber structure when building polarization maintaining components and patchcords.
