“…The research on mid-infrared (mid-IR) supercontinuum (SC) sources has drawn worldwide attention because of their great application potential in many areas such as spectroscopy [1], frequency metrology [2], remote sensing [3], and atom physics [4]. In the past decades, SC generation in silica glass fibers [5][6][7][8][9][10][11][12][13], especially in silica photonic crystal fibers (PCFs) [9][10][11][12][13], has been extensively studied due to the controllable dispersion property and low propagation loss in visible and near-IR regions. Soft glass optical fibers with high nonlinearity and low propagation loss in the mid-IR region, such as chalcogenide [14][15][16][17], tellurite [18][19][20], and fluoride [21][22][23][24][25][26][27][28][29] glasses, are needed for generating mid-IR SC.…”

We demonstrate an integrated all-fiber mid-infrared (mid-IR) supercontinuum (SC) source generated by a 1.95 μm master oscillator power amplifier system and a single-mode ZBLAN (ZrF 4 -BaF 2 -LaF 3 -AlF 3 -NaF) fiber. The maximum average output power is 10.67 W with spectral bandwidth covering from ∼1.9 to 4.1 μm. The single-mode ZBLAN fiber and silica fiber are thermal-spliced to enhance the robustness and practicability of the system. It is, to the best of our knowledge, the first high-power integrated compacted all-fiber mid-IR SC source based on thermal-spliced silica fiber and ZBLAN fiber. ©

Ultraflat-top midinfrared coherent broadband supercontinuum using all normal As 2 S 5 -borosilicate hybrid photonic crystal fiber," Opt. Eng. 55(6), 066109 (2016), Abstract. We report more than two octave spanning mid-IR flat-top supercontinuum (SC) generation using all normal As 2 S 5 -borosilicate hybrid photonic crystal fiber. Our design is based on a chalcogenide As 2 S 5 photonic crystal fiber (PCF), where the first ring composed of six air holes is made by borosilicate glass. By injecting 50-fs pulses with 1.6 nJ energy at 2.5 μm in the all normal dispersion (ANDi) regime, a flat-top broadband SC extending from 1 to 5 μm with high-spectral flatness of 8 dB is obtained in only 4-mm fiber length. To the best of our knowledge, we present the broadest flat mid-IR spectrum generated in the ANDi regime of an optical fiber. The self-phase modulation and the optical wave breaking are identified as the main broadening mechanisms. The obtained broadband light source can be potentially used in the field of spectroscopy and in high-resolution optical coherent tomography owing to the high-spectral SC flatness generated by our designed fiber.

, "Fiber-integrated tungsten disulfide saturable absorber (mirror) for pulsed fiber lasers," Opt. Eng. 55 (8) Abstract. We propose two schemes for achieving tungsten disulfide (WS 2 )-based saturable absorber (SA) and saturable absorber mirror (SAM). By utilizing the pulsed laser deposition method, we grow the WS 2 film on microfiber to form an evanescent field interaction SA device. Incorporating this SA device into a common ring-cavity erbium-doped fiber (EDF) laser, stably passive mode-locking can be achieved with pulse duration of 395 fs and signal-to-noise ratio of 64 dB. We also produce a fiber tip integrated WS 2 -SAM by utilizing the magnetron sputtering technique (MST). This new type of SAM combines the WS 2 layer as SA and gold mirror as high reflective mirror. By employing the WS 2 -SAM, we construct the linear-cavity EDF lasers, and achieve passive mode-locking operation with pulse duration of ∼1 ns and SNR of ∼61 dB. We further achieve stably passive Q-switching operation with pulse duration of ∼160 ns and pulse energy of 54.4 nJ. These fiber-integrated SAs and SAMs have merits of compactness and reliability, paving the way for the development of new photonic devices such as SAs for pulsed laser technology.
