Nonlinear Photonic Crystal Fiber
• Small mode field area
• High nonlinear coefficient
• Zero dispersion in visible wavelength range

This single mode nonlinear photonic crystal fiber combines a
very small effective mode field area (2 μm2) and zero dispersion
(around 750 nm) to allow efficient supercontinuum generation
with 800 nm pump sources. Furthermore the fiber is polarization maintaining for increased efficiency.
The fiber is available with hermetically sealed ends and FC/PC
connectors. It could also be spliced to standard single mode
fiber or large mode area PCF.

Typical Supercontinuum Output

Relative intensity [dB]

Photonic crystal fibers use a microstructured cladding region
with air holes to guide light in a pure silica core, giving rise to
novel functionalities.
