“…Apart from the large mode area and endless SM properties, purposeful manipulation of fiber structure endows PCFs with enhanced nonlinearity, modified dispersion, high birefringence, and other unique optical characteristics that facilitate their application to cover not only high power laser but also many other disparate fields such as nonlinear optics, [216] interferometry, [496] beam deliver, [497] sensing, [498,499] microscopy, [500] etc. For example, gas-filled hollow-core PCFs (HC-PCF) with flexible pressure tunability of the zero-dispersion wavelength (ZDW) allows the generation of supercontinuum from the deep-or vacuumultraviolet region [217,219] to mid-infrared.…”

High‐power laser sources are widely used in industrial precision processing and act as a new platform for strong‐field physics research using peak power over petawatt. This review focuses on realizing high‐energy solid‐state disk and slab systems and the nonlinear‐suppression strategies for high‐power fiber systems using the functional fibers. First, the implementations and enabling technologies of the solid‐state lasers for increasing peak power from gigawatt to petawatt are reviewed. Then the mechanisms and suppression strategies of the deterioration effects (including stimulated Raman scattering, stimulated Brillouin scattering, and transverse mode instability) in various fiber amplifiers are analyzed. At the same time, the mechanism and achievements of the current functional fibers are introduced. Finally, the challenges and perspectives of high‐power solid‐state and fiber amplifiers are summarized.

.A hollow-core negative curvature fiber (HC-NCF) with high birefringence for temperature sensing based on surface plasmon resonance effect is proposed. For the HC-NCF, the cladding layer is composed of six silica tubes, and the thickness and radius of the two silica tubes in the y-axis direction are different from those of other ones. Moreover, the two silica tubes in the y-axis direction are filled with the gold wires, and the ethanol to be tested is filled in other silica tubes and air area. As the temperature changes, the coupling state between the x-pol core mode and surface plasmon polarization mode will change. The temperature sensitivity can be up to 3.1 nm / ° C in the range of 20°C to 40°C. Moreover, the proposed HC-NCF temperature sensor simultaneously achieves the maximum R of 3.333 × 10 − 2 ° C and maximum FOM of 269 ° C − 1, which indicates that it has high sensitivity, good linearity, high R, and large FOM. The proposed HC-NCF temperature sensor is expected to be useful in the field of the environmental monitoring.

“…High-birefringence and singlepolarization were achieved either by using multiple nested resonators [18], [21] or high index materials in the cladding [19], [20]. Most recently, a four-fold [21] and six-fold [22] symmetry bi-thickness HC-ARF were experimentally reported with outstanding optical performances. For example, in [21], a phase birefringence of 2.35 × 10 −5 and 9.1 × 10 −5 at 1550 and 1589 nm were achieved respectively.…”

In this letter, to the best of our knowledge, a new type of hollow-core anti-resonant fiber (HC-ARF) design using hybrid silica/chalcogenide cladding is presented for singlepolarization, high-birefringence, and endlessly single-mode operation at 2 m wavelength. We show that the inclusion of a chalcogenide layer in the cladding allows strong suppression of -polarization, while maintaining low propagation loss and singlemode propagation for -polarization. The optimized HC-ARF design includes a combination of low propagation loss, highbirefringence, and polarization-extinction ratio (PER) or loss ratio of 0.02 dB/m, 1.2×10 −4 , >550 respectively, while the loss of the -polarization is >20 dB/m. The proposed fiber may also be coiled to small bend radii while maintaining low bend-loss of ≈ 0.01-0.1 dB/m, and can potentially be used as polarization filter based on the different gap separations and bend conditions.
