Generation of wide-bandwidth pulse with graphene saturable absorber based on tapered fiber |
|
| Abstract: | Wide-bandwidth pulses were generated with a dispersion-managed erbium-doped passively mode-locked fiber laser based on a graphene saturable absorber. The graphene saturable absorber was composed of a tapered fiber deposited with graphene fabricated by liquid-phase exfoliation. The output pulse had a 3-dB bandwidth of 13.6 nm, which is the widest spectrum ever achieved with graphene-tapered-fiber saturable absorbers. |
