| Summary: | A wide-band supercontinuum source generated by mode-locked pulses injected into a Highly
Non-Linear Fiber (HNLF) is proposed and demonstrated. A 49 cm long Bismuth–Erbium Doped Fiber
(Bi–EDF) pumped by two 1480 nm laser diodes acts as the active gain medium for a ring fiber laser,
from which mode-locked pulses are obtained using the Non-Polarization Rotation (NPR) technique. The
mode-locked pulses are then injected into a 100 m long HLNF with a dispersion of 0.15 ps/nm km at
1550 nm to generate a supercontinuum spectrum spanning from 1340 nm to more than 1680 nm with
a pulse width of 0.08 ps and an average power of 17 dBm. The supercontinuum spectrum is sliced
using a 24 channel Arrayed Waveguide Grating (AWG) with a channel spacing of 100 GHz to obtain a
fanned-out laser output covering the O-, E-, S-, C-, L- and U-bands. The lasing wavelengths obtained
have an average pulse width of 9 ps with only minor fluctuations and a mode-locked repetition rate of
40 MHz, and is sufficiently stable to be used in a variety of sensing and communication applications,
most notably as cost-effective sources for Fiber-to-the-Home (FTTH) networks |
