Large mode area photonic crystal fibers

The selection of Crystal Fiber Large Mode Area fibers covers a range of fibers for diffraction-limited high power delivery. The large mode area enables high power levels without nonlinear effects or material damage.

With standard technology, you have to trade large mode areas for single-mode operation, but the Crystal Fiber Large Mode Area fibers provide single-mode operation in a large wavelength range – endlessly single-mode operation.

For fibers with connectors, please see our aeroGUIDE patch cords or the SuperK CONNECT fiber delivery system.

The fibers are also available in polarizing and polarization-maintaining versions.

Features

  • Endlessly single-mode operation – no higher-order mode cut-off
  • Handles very high average power as well as high peak power
  • Low nonlinearities
  • Low fiber loss
  • Mode field diameter is wavelength-independent
  • Available with core sizes from 5 to 25 microns
