26 July 2011Supercontinuum generation by using photonic crystal fibres made from borosilicate glasses
In this work, we present results of broadband emissions ranging from 800 to 1500 nm
generated by using Photonic Crystal Fibres (PCFs) made from borosilicate glasses. The borosilicate
PCFs, fabricated by the Stack-and-Draw technique, consist of five hollow ring periods around the solid
core. The solid core is based on the lead-doped borosilicate glass. The PCFs with their external
diameters ranging from about 3.8 to 6 microns were excited with a commercial pulsed diode laser
(wavelength at 1065 nm, Power <100mW). The PCF length used to generate broadband emissions was
less than a meter. The Optical Attenuation of these PCFs was measured via the Cut-Back method and
their Dispersion Spectra were calculated by using the Finite Element Method (FEM) and the scanning
electronic microscope images. Finally, we believe that short borosilicate PCFs with lead-doped cores
(related to high non-linear properties) may be used in broadband emissions, supercontinuum
generations or other non-linear applications.
