Summary: The characteristics of higher-order modes in a 7-cell HC-PBF were investigated, revealing the non-degenerate phenomenon of HE21. An optimized 7-cell HC-PBF supporting 6 modes was developed through theoretical analysis. Additionally, bending losses of all HOMs in the fiber were measured, with marked bending loss not observed even at a small bending radius of 0.5 cm, distinguishing it from a solid core four-mode fiber.

Summary: Hollow-core optical fibers convey light in air, showing remarkably low sensitivity of the propagation delay to temperature changes, especially in photonic bandgap type. The residual variation in propagation delay observed near the zero sensitivity wavelength has no apparent correlation to imposed temperature changes. Practical thermal stability of latency is limited by polarization mode dispersion, with strong polarization mode coupling observed in addition to birefringence.

Summary: In this article, a hollow-core photonic crystal fiber (HCPCF) ring resonator based on a spatial coupling method was proposed, with a small component size of 22 x 30 x 6 mm³. By using a 7-core photonic crystal fiber with a mode field diameter of 10μm, a ring resonator with a measured finesse of 18 and a low coupling loss of 0.41 dB was achieved. The practicality of the HCPCF gyro was enhanced by using a highly integrated free space silicon optical bench manufactured by deep silicon etching and tiny optical lens package technology. Moreover, the article investigates two important factors affecting the spatial optical coupling efficiency, lens type and fiber mode field size, providing instructive results for all spatial optical coupling systems.

Summary: The study demonstrates an in-line polarization controller designed for hollow core photonic bandgap fiber, which involves inserting a length of the fiber into a standard 3-paddle controller commonly used for polarization control using single mode fibers. Despite the difference in operational principles when using hollow core photonic bandgap fiber instead of SMF, effective polarization control can still be achieved effortlessly.

Summary: The unique characteristics of hollow core fibers make them attractive for designing inline fiber optic devices. We report a novel approach that uses a resonant band of single-ring antiresonant fiber to realize a high-performance hollow-core fiber polarizer. The device offers low transmission loss and a high polarization extinction ratio. These results encourage further development of other hollow-core fiber components.

Summary: The rotational stimulated Raman scattering of hydrogen molecules in an all-fiber cavity based on hollow-core photonic crystal fibers was reported. By using a homemade 1064 nm pulsed fiber amplifier, rotational SRS was induced in the gas cavity, leading to the generation of a 1135 nm Stokes wave. The output characteristics were explored by adjusting the pulse width and repetition frequency of the pump source, while a theoretical model was established for comparison with experimental results, facilitating the application of gas Raman laser based on HC-PCFs.

Summary: Localized gap modes in one-dimensional coherent atomic gases were theoretically investigated using Lambda-type three-level configuration and the multiple scales method. Fundamental gap solitons and dipole gap modes were discovered, and their (in)stability regions in the band-gap spectrum were confirmed through systematic numerical simulations. These predicted results may expand the nonlinear horizon in coherent atomic gases and provide new opportunities for optical communication and information processing.

Summary: Electromagnetically induced moire optical lattices, generated in a three-level coherent atomic gas using electromagnetically induced transparency, have attracted significant interest recently. By changing the twisted angle and relative strength between two constitutive sublattices, extremely flattened moire Bloch bands can always appear, resembling the typical flat-band and moire physics found in other contexts. The dynamics of light propagation in the induced periodic structures demonstrate unique linear localization and delocalization properties. The predicted moire optical lattices and flattened bands can be observed in a Rubidium atomic medium.

Summary: In rotation-resolved N+2 lasing, we observe an unexpected experimental phenomenon that the R-branch lasing intensity from a single rotational state near 391 nm can be much stronger than the sum of P-branch lasing intensities from all rotational states at suitable pressures. Through combined measurements of the dependence of rotation-resolved lasing intensity on pump-probe delay and rotation-resolved polarization, we speculate that the destructive interference may occur for spectrally-indistinguishable P-branch lasing due to propagation effect, while R-branch lasing is minimally affected due to its discrete spectral property, after ruling out the role of rotational coherence. These findings shed light on the physics of air lasing and provide a feasible approach to manipulate air lasing intensity.
