In this paper, we propose a photonic crystal fiber with broadband ultra-flattened normal dispersion at 2 μm. In this fiber, a subwavelength air hole in the core region and air holes arrangement in the cladding region are used to control the property of dispersion. With optimized design, the dispersion of the proposed ultra-flattened normal dispersion fiber (UNDF) can be kept within-72.4 to-73.15 ps•nm-1 km-1 from 1750 to 2350 nm wavelength. Benefiting from this advantage, the fiber shows great potential in the applications of coherent supercontinuum (SC) generation and dissipative soliton resonance (DSR) generation in thulium-doped fiber lasers. According to our investigation, coherent SC with 10-dB bandwidth of 238 nm can be obtained by using 50-cm UNDF. Furthermore, by constructing a UNDFbased nonlinear optical loop mirror as a saturable absorber, we specifically investigate the field evolution from dissipative soliton to DSR in passively mode-locked lasers. The proposed UNDF can be a key component for various laser sources in a 2-μm band.

“…The authors have shown that a nearly zero flattened chromatic dispersion profile in the band 2 to 3.5 μm can be achieved through a proper design of the PCF cladding region. Furthermore, Gao et al 14 designed a ZBLAN PCF with a large negative chromatic dispersion value of −351.3 ps∕km∕nm and confinement loss as low as 0.05 dB/km at 2.9 μm. In addition, the authors have demonstrated, via numerical simulations, that stretched optical pulses with a compressed duration of 1.56 ps are realized using the proposed PCF as a dispersion compensator device in a mode-locked fiber laser.…”

We numerically investigate coherent supercontinuum (SC) generation extending from the deep ultraviolet to the mid-infrared spectral region using few-cycle optical pulses, pumped into a ZBLAN photonic crystal fiber. The finite difference method is used to optimize the fiber structure and achieve two zero dispersion wavelengths, with a broad anomalous dispersion region. The propagation of ultrashort pulses and their nonlinear dynamics is accurately modeled by employing the forward unidirectional propagation equation for the analytic signal of the pulse electric field. We show that by pumping in the anomalous regime of dispersion, the high-order solitons undergo an implosion process and spectral broadening is achieved via the contribution of self-phase modulation, self-steepening, and shock formation, along with a strong transfer of energy into a nonsolitonic resonant Cherenkov-like radiation in the normal dispersion region. Furthermore, numerical results indicate that broadband supercontinua spanning the region from 0.22 to 4.6 μm is successfully achieved with a pulse having a soliton order and duration of 12 and 6 fs, respectively. In addition, the deterministic feature of the implosion mechanism exhibits very low sensitivity to the input quantum noise and achieves excellent coherence properties. The proposed multioctave SC source is found promising for various potential applications, such as two-photon excited autofluorescence, bioimaging, spectroscopy, optical signal processing, and medicine.
