Summary: This study reports the first distributed acoustic sensing (DAS) experiment with a transmission distance of over 1,000 km. The experiment used a hybrid link consisting of field and lab fibers with bi-directional inline Raman amplification. A frequency-diversity chirped-pulse system was employed for the probe signal, and the Rayleigh backscatter was recovered using a coherent receiver with correlation detection and diversity combining. The experiment achieved a measurand resolution of approximately 100 p epsilon/root Hz at a gauge length of 20 meters in offline testing. In addition, the study demonstrated the first real-time FPGA implementation of chirped-pulse DAS without frequency diversity, covering a range of 210 km.

Summary: The study focuses on the emission properties of CaZnOS crystals single doped with Terbium and co-doped with Terbium and Europium. By investigating optical properties and time-resolved luminescence, the de-excitation mechanisms and charge transfer processes have been established, allowing tuning of emission properties. It also shows that mechanical stimulus can induce mechano-luminescence following the same path as photoluminescence, with precise tuning of emission across the visible spectrum.

Summary: A self-started dual-wavelength fiber laser was developed using a nonlinear amplifying loop mirror and a Lyot filter to address issues such as nonlinear phase accumulation, dual-wavelength competition, and crosstalk between the mode-locking mechanism and filtering effect. Through temperature control of a specific polarization-maintaining fiber, the laser can be continuously tuned within a wavelength range and demonstrate mutual coherence of the dual-wavelength pulses. The laser shows improved long-term stability and repeatability, which will benefit high-power or field applications of dual-comb spectroscopy.

Summary: An optically readable electrochromic-based microfiber synaptic device was designed by combining a multimode fiber and an electrochromic device, which can control the transmission of light in the fiber using an external voltage. This device has the ability to imitate various basic functions of biological synapses, such as synaptic plasticity, paired-pulse facilitation (PPF), and the transition from short-term memory to long-term memory. Additionally, the device decodes the output optical signal with the international Morse code and can be integrated into a more complex and versatile photonic neuromorphic system.

Summary: We have developed a silica-based large mode area fiber with a nanostructured core for use in fiber laser cavities. Our experimental results demonstrate that the fiber operates in single mode with low bending loss. We have also successfully fabricated high reflectivity UV induced fiber Bragg gratings and utilized them in a fiber laser setup. The flexibility of the nanostructuring approach holds promise for the development of passive fiber components that can be matched with any type of active fibers.

Summary: This paper presents the first fiber Bragg grating (FBG) inscribed in a polarization maintaining (PM) optical fiber with an artificially anisotropic core achieved by distributing discrete germanium-doped areas in nanoscale. The FBG has unique properties, similar to those of a grating in a cylindrically symmetrical optical fiber, despite being written in a fiber that preserves the orthogonal polarization components of the mode. The FBG is insensitive to the excited polarization state and twist due to the relatively low birefringence of the fiber, making it suitable for all-fiber lasers, polarization fiber sensors, and components with spectral insensitivity to twist.

Summary: We have prepared and characterized microstructured biodegradable and biocompatible polymer optical fibers using commercially available poly(D,L-lactic acid) (PDLLA). The preparation of preforms by transfer molding and fiber manufacturing was reported and the influence of polymer processing on the molar mass decrease of PDLLA was investigated. The in vitro degradation of the fabricated fibers in phosphate buffered saline (PBS) was studied, showing molar mass loss of 21%, 25%, and 43% over 105 days for fibers with diameters of 400, 200, and 100 μm, respectively. Cutback measurements revealed an attenuation coefficient of 0.065 dB/cm at 898 nm for a microstructured fiber with a diameter of 219 +/- 27 μm. After immersion in PBS at 37 degrees C, the optical loss increased by 0.4 dB/cm at 950 nm after 6 h and by 0.8 dB/cm after 17 h.

Summary: The reactions of [(thf)(2)TiCl4] with sodiated 2,2'-bis[2-hydroxy-3,5-di(tert-butyl)benzylideneamino]-1,1'-biphenyl (1 a) and 2,2'-bis[2-hydroxy-3,5-di(tert-butyl)benzylideneamino]-4,4'-dimethyl-1,1'-biphenyl (1 b) yield the corresponding Ti complexes 2 a and 2 b. Similarly, 1 a reacts with [(thf)(2)ZrCl4] to the corresponding Zr derivative 3. For 2 a, a mixture of cis-beta and trans isomers were observed in solution whereas the Zr congener exclusively forms the cis-alpha form. Quantum chemical calculations verify that these isomers are the preferred molecular structures. The crystal structures of cis-beta isomeric 2 a and cis-alpha isomeric 3 have been determined. Metalation of 1 a with Ti(NMe2)(4) yields 2,2'-bis[(2-oxido-3,5-di(tert-butyl)phenyl)-dimethylaminomethylamino]-1,1'-biphenyl titanium(IV) (4) with a hexadentate ligand.

Summary: Magnesium and calcium are too inert to directly deprotonate amines, so alternative strategies are needed for the synthesis of bulky amides. N-bound trialkylsilyl groups have been used to facilitate metalation reactions. In situ Grignard reagent formation in THF with magnesium or calcium, hydryl halide, and imine allows the synthesis of amides with bulky silyl-free substituents. Ball milling protocols may lead to competing side reactions like aza-pinacol coupling reactions. Calcium is a better choice for in situ Grignard reagent formation and subsequent addition to imines, while heavier alkaline-earth metals strontium and barium are less selective, leading to competitive aza-pinacol coupling reactions. Solid-state molecular structures of [(Et2O)Mg(N(Ph)(CHPh2)(2)] and [(Et2O)(2)Ca(N(Ph)(CHPh2)(2)] have been determined.

Summary: The alkaline-earth metalation of dimesitylphosphane oxide Mes(2)P(O)H in ethereal solvents with dialkylmagnesium and alkylmagnesium bromide, as well as the homoleptic bis(trimethylsilyl)amides of calcium, strontium, and barium, produces various complexes depending on the stoichiometry. The exchange of ligands in one of the complexes allows the isolation of different compounds. In ethereal solutions, the heteroleptic complexes undergo Schlenk-type equilibria, interconverting into their homoleptic counterparts.
