Abstract
In this work, a supercontinuum (SC) source is proposed and demonstrated using a highly-doped, 2âm long zirconia-erbium doped fiber (Zr-EDF) with a dopant concentration of 3800âppm/wt and a narrow core 100âm long single-mode-fiber (SMF). A graphene based saturable absorber (SA) is used as a passive mode-locker, generating pulses with an average output power, pulse energy and peak power of â¼0.9âmW, â¼69.8âpJ and â¼83âW respectively and a repetition rate of 12.9âMHz. This is then amplified using a 140âmW amplifier, giving an output power, pulse energy and peak power of â¼75.0âmW, 5.8ânJ and â¼6.76âkW respectively and injected into a 100âm long SMF, to generate an SC output which spans from 1450 to more than 1700ânm, with a pulse width at its full-width-at-half-maximum (FWHM) of 120 fs, 7 times lower than the 840âfs FWHM width of the pulses from the fiber laser. The narrow core SMF performs comparably to longer lengths of standard SMF-28 fibers.
