Welcome to our website, www.supercontinuum.pl

We synthesize multicomponent oxide glasses for mid-infrared spectral range and we develop our own technology of nanostructured microoptical elements and nonlinear photonic crystal fibers. We investigate conditions of supercontinuum generation in our own fiber structures.

Abstract: Experimental demonstration of supercontinuum in an in-house fabricated, all-solid, flat-top normal dispersion photonic crystal fiber is given. Presented study comprises characterization of developed fiber in terms of microstructure design, attenuation and dispersion characteristic, followed by experiment and numerical analysis of supercontinuum generation spanning an octave from around 900 nm to 2400 nm under 1530 nm excitation with 70 fs pulses.
