Summary: The micro-machining technique using focused ion beam milling on nodeless anti-resonant hollow-core fiber allows for the creation of a deep fluidic channel, providing direct access for liquid/gas into the hollow-core region. This novel design enables the splicing of nodeless anti-resonant hollow-core fibers with solid-core fibers while preserving the fluidic channel, with simulations showing no additional loss induced by the milled hole.

Summary: A small-scale delivery medium for CO2 laser energy is developed, which exhibits stable performance, flexibility, and high-strength. It is particularly important in extreme laser processing environments and minimally invasive surgery in high-humidity, twisty and narrow channels. The developed multimaterial infrared fibers can stably deliver CO2 laser energy and are suitable for fabric cutting and bio-tissues ablation.

Summary: The study investigated the issue of SOP drift in active tapered double-clad fibers under intense pumping, finding that the birefringence of active fibers is highly dependent on the pump power. By introducing an active double-clad fiber with low intrinsic birefringence, the research demonstrated that the SOP and DOP remained more stable in sT-DCF compared to other types of fibers. Additionally, an active sT-DCF showed efficient amplification in a picosecond master-oscillator power-amplifier scheme, delivering 50 ps pulses at 1040 nm with high average power and beam quality.

Summary: The methodology introduces a design for a multipoint fiber refractometer utilizing the C-OFDR technique, where nonlinearity effects are reduced by cutting the processed signal length in a scanning cycle and ensuring integer cycles for interference signals. This design approach leads to stable and strong sensing signals, demonstrating the possibility of a multipoint refractometer.

Summary: This paper proposes a highly birefringent and low-loss hollow-core anti-resonant fiber (HC-ARF) with a hybrid guidance mechanism. The fiber is designed using twin symmetrical and mutually tangential elliptical arc anti-resonance layers (EA-ARLs) in a conventional 8-tube HC-ARF. Simulation results show that the proposed HC-ARF achieves high birefringence and low confinement loss, making it suitable for applications in the near-infrared range.

Summary: In this study, a system is proposed where a quantized light field interacts with a two-level atomic ensemble coupled by microwave fields in optical cavities, described by a generalized Dicke model. It is shown that there exist multicritical points for the superradiant quantum phase transition, which can be effectively manipulated through system parameter tuning. Furthermore, it is found that the quantum critical points can evolve into a Lifshitz point if the Rabi frequency of the light field is modulated periodically in time, and the texture of atomic pseudo-spins can be used to characterize the quantum critical behaviors of the system. These results are of great significance for revealing intriguing physics of quantum phase transitions and exploring novel quantum multicritical phenomena based on the generalized Dicke model.

Summary: This paper introduces a low-loss, high birefringence anti-resonant fiber structure that maintains a birefringence above the 10-3 level over a wide frequency band. It has minimum loss and bend radius and good manufacturing error tolerance. Additionally, three methods for introducing high birefringence into low-loss ARFs are proposed and verified, contributing to the development of more efficient and reliable THz transmission systems.

Summary: We experimentally study a gas of quantum degenerate 87Rb atoms in the full dimensional crossover and observe the phase fluctuations through power spectrum measurements. We confirm that the chemical potential and temperature control the system's departure from three-dimensional behavior. Our study quantitatively observes the disappearance of temperature dependence as the system becomes three-dimensional, with fluctuations determined by the occupation of one-dimensional axial collective excitations.
