Large Mode Area photonic crystal fibers

Our Large Mode Area photonic crystal fibers are designed for diffraction-limited high-power delivery. The large mode area prevents nonlinear effects and material damage.

With standard fibers, you trade large mode areas for single-mode operation. With our Large Mode Area fibers, you get single-mode operation in a wide range of wavelengths.

Key Features

Endlessly single-mode operation

Handles high powers

Low nonlinearities

Low fiber loss

Wavelength-independent MFD

Core sizes from 5 to 25 microns

With standard technology, you trade large mode areas for single-mode operation. But our crystal fiber Large Mode Area fibers provide single-mode operation in a wide wavelength range.

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

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