Nonlinear Photonic Crystal Fibers for Supercontinuum Generation

Discover NKT Photonics' nonlinear photonic crystal fibers, optimized for supercontinuum generation and nonlinear wavelength conversion. These fibers feature a tailored dispersion profile and high nonlinear coefficient, making them ideal for various applications.

Nonlinear photonic crystal fibers

Our nonlinear photonic crystal fibers are optimized for supercontinuum generation and nonlinear wavelength conversion. You get a unique combination of a tailored dispersion profile and a very high nonlinear coefficient.

We offer single-mode supercontinuum fibers optimized for the several common pumping laser wavelengths. We also offer some of our PCF fibers as modules with hermetically sealed ends – See our femtoWHITE product range.

Nonlinear supercontinuum fibers

We offer single-mode supercontinuum fibers optimized for all important pumping laser wavelengths. The majority of our nonlinear fibers are available with hermetically sealed ends and FC/PC connectors.

These single-mode non-linear photonic crystal fibers combine a very small effective mode field area and low/zero-dispersion to allow efficient supercontinuum generation with 800 nm and 1064 nm pump sources.
