Graphene filament-chitin bio-composite polymer based passive Q-switcher in EDFL with tunable wavelength

The generation of pulsed fiber laser and its wavelength tunability using graphene based three-dimensional (3D) printer filament embedded in chitin bio-polymer as passive saturable absorber (SA) in the 1.5 um region was successfully demonstrated. The SA was prepared by extruding the graphene filament...
