Abstract
The new generation of broadband wavelength-division-multiplexed (WDM) transmission system requires to ensure fiber properties are as equal as possible over the faster broadening communication window. In this paper we focus our attention on investigating a fiber design suitable for broadband non-linear process, in particular we will devote our analyses to broadband super-continuum generation. In fact supercontinuum (SC) based devices have recently attracted great interest for their potentiality in many applications such as DWDM sources for long-distances transmission1,2 2-R all-optical regenerator, 3 TDM applications, 4 OC-192 data stream down conversion, 5 and medical applications. In this technique a seed pulse train broads its spectrum by non-linear effects in a suitable fiber. The SC spectrum can be sliced by an arrayed-waveguide-grating to obtain several channels, by a broadband filter to obtain short pulses for TDM applications or by a suitable filter to recover the initial pulse shape.
