The continuous improvement of interferometric gravitational-wave detectors (GWDs) and the preparations for next generation of GWDs set highly demanding requirements on their laser sources. A promising candidate to fulfill the challenging requirements of GWD laser sources is the hybrid master-oscillator power fiber amplifier (MOPFA) configuration. The implementation of a MOPFA relies principally on commercial silica glass-based optical fiber technology, which has been key in the successful development of high-power fiber amplifiers but that poses also a limitation to power scaling of these devices. It is well known that erbium (Er) ions tend to cluster in silica glass leading to ion-ion interactions and degradation of performance. The limited concentration of RE ions per unit length implies a limited optical gain per unit length and thus the requirement for long amplifying fiber lengths that enforce deleterious nonlinear effects, foremost stimulated Brillouin scattering (SBS). Numerous SBS suppression techniques have been proposed, alongside investigation of specialty optical fibers. One of the most promising solutions is the use of highly doped optical fibers based on multicomponent phosphate glass that allows the fabrication of ultra-compact active devices with minimized nonlinearities. To realize compact optical fiber amplifiers operating at 1.5 µm, a series of highly Er3+-doped custom phosphate glass compositions was designed and fabricated to be used as active materials for the core of the fiber amplifiers. Suitable cladding compositions were explored. Core and cladding glasses were synthesized by melt-quenching method. The core glass was cast into a cylindrical mold to form a rod, whereas the cladding tube was fabricated by extrusion technique. Phosphate fibers were then manufactured by drawing the preform assembled by rod-in-tube technique. Preliminary results of the application of the Er3+-doped phosphate fiber as laser active medium in a fully monolithic single-mode single-frequency core-pumped MOPFA setup resonantly pumped at around 1480 nm are presented.

The well-known enhancement effect of surface-enhanced Raman spectroscopy (SERS) is associated with the presence of metallic nanostructures at the substrate surface. Different bottom-up and top-down processes have been proposed to impart the substrate with such a nanostructured layer. The former approaches are low cost but may suffer from reusability and stability. The latter strategies are expensive, time consuming and require special equipment that complicate the fabrication process. Here, we present the possibility to obtain stable and reusable SERS substrates by a low-cost silver-sodium ion-exchange process in soda-lime glass microrods. The microrods were obtained by cutting the tip of the ion-exchanged soda-lime fiber, resulting in disks of about few millimeters in length and one hundred microns in diameter. A thermal annealing post-process was applied to trigger the reduction of Ag+ ions into nanoparticles (AgNPs) within the ion-exchanged glass microrods. Afterwards, ion-exchange and thermal treatments were carefully tuned to assure the presence of silver NPs exposed on the surface of the microrods, without using any chemical etching. An AFM analysis confirmed the presence of AgNPs with size of tens of nm on the surface of the fiber probe. A SERS affinity bioassay was developed on the probe with the final aim of detecting microRNA fragments acting as biomarkers of different diseases. Specifically a DNA hybridization assay was built up by anchoring a molecular beacon containing a Raman tag on the Ag surface via thiol chemistry. Initial SERS experiments confirmed the presence of the beacon on the NPs embedded on the microrods surface, as monitored by detecting main spectral bands ascribed to the oligonucleotide chain. Finally, the ability of the platform to interact with the target microRNA sequence was assessed. The analysis was repeated on a number of miRNA sequences differing from the target to evaluate the specificity of the proposed assay.

Optical fibers have been employed for several years in biomedicine and mainly used for light delivery and collection with high efficiency and selectivity. So far most of the research effort has been devoted to the optical configurations and the functions of the fibers rather than on the materials employed. Indeed, this aspect has been mainly considered to assure biocompatibility with tissues and non-toxic behavior limiting the choice mostly to silicate fibers. We report on the recent advances in engineering inorganic glass optical and hollow fibers fabricated with optical glasses which are also resorbable in body fluids. Suitable phosphate glass compositions were designed to combine resorbability and optical transparency. Glasses were fabricated by melt-quenching inside a chamber furnace under a flux of dried air and cast into preheated brass molds. The fibers were obtained by preform drawing, with the core rod fabricated by melt quenching whilst the cladding tube by rotational casting. Extrusion techniques were also applied to obtain more complex cross sections with increased functionalities. Glasses and fibers were characterized in their physical and optical properties. The materials showed high stability toward crystallization and a wide optical transmission window, ranging from the ultraviolet to the near infrared wavelength regions. Hollow fibers were employed to demonstrate multifunctional fiber probes, able to provide drug delivery and light excitation in the prospect of developing resorbable endoscopes for intravital monitoring and therapy, such as photodynamic therapy. Optimization of drug delivery was carried out using functionalization procedures on the surface of both bulk glasses and hollow fibers, aiming to modify the release kinetics: a silanization protocol was developed and successfully tested using different organic compounds. The modification of the surface roughness was monitored using atomic force microscopy, while surface energy changes verified using contact angle measurements. The possibility of performing drug excitation was assessed by guiding light through the capillary using optical beams produced by different wavelength sources covering the visible spectrum. Finally, mechanical characterization of the prepared optical fibers and hollow fibers was carried out to measure the elastic moduli, the tensile strength and the minimum radius of curvature attainable. The overall results allowed to demonstrate the reliability of the proposed optical fibers and hollow fibers for biomedical applications.
