“…The optical bandwidth and FSR of the FFP filter are about 50 pm (~6.25 GHz) and 110 nm, respectively. Since the gain bandwidth of Bi-EDF is less than 110 nm [9], only one wavelength in the fiber ring laser cavity will be excited. The insertion loss of the FFP filter at the peak of the pass-band is about 2.2 dB.…”

“…In order to achieve better mode field diameter matching, both ends of the Bi-EDF were first fusion spliced to high numerical aperture (NA) SiO 2 fibers (HI980, Corning) before being spliced to conventional SiO 2 fibers (SMF28, Corning). Thus, the fiber-tofiber loss at 1310 nm was 2.3 dB [11], [13]. The Bi-EDF was bidirectionally pumped with two high power laser diodes (LDs).…”

Wavelength-Tunable and Bandwidth-Variable Ultra-Flat Optical Frequency Comb Block Generation From a Bismuth-Based Actively Mode-Locked Fiber Laser

We generate, for the first time and to the best of our knowledge, a tunable ultraflat optical frequency comb (OFC) block from a 10-GHz bismuth-based actively modelocked fiber laser. A bismuth-based erbium-doped fiber (Bi-EDF) with a length of 1.5 m and a bismuth-based highly nonlinear fiber (Bi-HNLF) with a length of 4.1 m are used as a gain medium and a spectral broadening device, respectively. We also employ a wavelengthtunable and bandwidth-variable optical filter for an intracavity filter. The center wavelength of the OFC output can be widely tuned from 1535 to 1585 nm because the Bi-EDF has a broadband gain profile. A spectrally broadened ultra-flat OFC is successfully generated by the self-phase modulation in the Bi-HNLF. By tuning the filter bandwidth, the 10-dB spectral width and the pulsewidth of the generated OFC can be widely varied from 0.23 to 2.4 nm and from 3 to 20.1 ps, respectively. The fiber ring cavity is as short as 17.8 m. For the entire tuning ranges, the proposed bismuth-based tunable ultra-flat OFC generator also realizes stable bit-error-free mode-locking operation.

“…Recently, broadband wavelength-tunable fiber lasers play the key role in the related applications of optical device testing, wavelength-division-multiplexing (WDM) communication, and fiber sensor system [1,2]. In general, the fiber Fabry-Perot filter (FFPF), tunable bandpass filter (TBF), and fiber Bragg grating (FBG) could be used in the fiber ring cavity for wavelength lasing and tuning, when the erbium-doped fiber amplifier (EDFA), Raman amplifier (RA), semiconductor optical amplifier (SOA) and hybrid optical amplifier were used inside cavity acting as gain medium [3][4][5][6].…”
