Graphene-based mode-locked spectrum-tunable fiber laser using mach–zehnder filter
An ultrafast spectrum-tunable fiber laser using a tunable Mach–Zehnder filter (TMZF) and a graphene-based saturable absorber as a mode-locking element is proposed and demonstrated. The proposed laser uses a 2-m-long zirconia–erbium-doped fiber (Zr-EDF) as the primary gain medium. The Zr-EDF has a...

description |
An ultrafast spectrum-tunable fiber laser using a tunable Mach–Zehnder filter
(TMZF) and a graphene-based saturable absorber as a mode-locking element is proposed and demonstrated. The proposed laser uses a 2-m-long zirconia–erbium-doped
fiber (Zr-EDF) as the primary gain medium. The Zr-EDF has a dopant concentration of
3800 ppm/wt and an absorption rate of 18.3 dB/m at 980 nm. The proposed laser is able
to generate mode-locked solitons, with the central wavelength of the spectrum tunable
from 1551 to 1570 nm and covering a wavelength range of about 19 nm. Sidebands are
observed with 3-dB bandwidths and pulsewidths of between 3.4 and 3.6 nm and from
730 to 780 fs, respectively, as well as a time–bandwidth product between 0.32 and 0.33.
The generated pulse yields an average output power value of 1.4 mW, pulse energy of
128 pJ, and repetition rate of 10.9 MHz. This is the first time, to the knowledge of the
authors, that a graphene-based mode-locked spectrum-tunable fiber laser is demonstrated
using a TMZF. |
