“…The concept shows a significant degree of integration, allowing to anticipate applications of the discussed HCWs in areas such as bioanalytics (e.g., on-chip analytics), quantum technologies (e.g., analysis of alkali vapor) or life sciences (e.g., nanoparticle tracking analysis). From an optofluidic perspective, the concept leads to novel lab-on-a-chip devices with new and improved functionalities for microfluidics, e.g., for waveguide-based nanoparticle tracking analysis. ,, It is important to note that the fields outside the waveguide core are very weak and therefore irrelevant for many applications. Due to the small overlap of the optical field with the polymer, additional applications at mid-IR wavelengths can be expected in the context of fingerprint spectroscopy within liquid and gaseous environments.…”

Higher-order modes and hollow-core waveguides are highly relevant research directions in photonics, while most studies are solely focused on fundamental modes. This work introduces a novel approach to efficiently excite higher-order modes in nanoprinted hollow-core waveguides using spatially controlled phase modulation. The key lies in the integration of precisely designed nanoprinted phase elements at the beginning of an antiresonant waveguide, which creates a spatially controlled phase shift that matches the phase distribution of the desired mode. Both experiments and simulations confirm efficient excitation of specific higher-order modes and verify antiresonant light guidance within the core. The study details all aspects of this approach, including a mathematical model explaining the importance of phase matching, simulations demonstrating the effect of the phase elements, and experimental verification using 3D nanoprinting and optical characterization. This approach enables the precise excitation of selected higher-order modes in a nanoprinted hollow-core waveguide, combining several key features in an integrated on-chip photonic platform with a small geometric footprint. Potential applications span across multiple disciplines, including nanoscience, analytical chemistry, and materials science. The flexibility of the concept and implementation method allows for transferring it to other types of on-chip waveguides and optical fibers, opening up new avenues for waveguide photonics.

Optical fibre sensors are an essential subset of optical fibre technology, designed specifically for sensing and measuring several physical parameters. These sensors offer unique advantages over traditional sensors, making them gradually more valuable in a wide range of applications. They can detect extremely small variations in the physical parameters they are designed to measure, such as analytes in the case of biosensing. This high sensitivity allows them to detect subtle variations in temperature, pressure, strain, the refractive index of analytes, vibration, and other environmental factors with exceptional accuracy. Moreover, these sensors enable remote sensing capabilities. Since light signals are used to carry information, the sensing elements can be placed at distant or inaccessible sites and still communicate the data back to the central monitoring system without signal degradation. In recent times, different attractive configurations and approaches have been proposed to enhance the sensitivity of the optical fibre-based sensor and are briefly explained in this review. However, we believe that the choice of optical fibre sensor configuration should be designated based on the specific application. As these sensors continue to evolve and improve, they will play an increasingly vital role in critical monitoring and control applications across various industries.
