A novel dispersion compensating fiber with multiple windows based on hybrid photonic crystal fiber

摘要

A novel dispersion compensating fiber with multiple windows is firstly proposed. The proposed DCF is based on hybrid photonic crystal fiber. This type of DCF gets a multiple negative dispersion windows by the coupling between the hybrid guiding mode in the edge of each band-gap and the index guiding mode in the cladding deficit area. This is very different from the ordinary dual-core mechanism. This proposed DCF can be widely used in dispersion compensating system, the photonic generation of UWB signals, the pulse forming system and the compressing of optical soliton.
