Due to the large scientific and technical interest in the mid-infrared (MIR) spectral region, and the limitations of MIR light sources, we focus on the generation of a broad supercontinuum inside a short piece of AsSe microstructured optical fiber (MOF) with a square lattice. This is accomplished by filling the holes in the innermost ring of the proposed MOF with GeAsSe to produce ultraflat and near-zero dispersion. Simulations reveal that, by launching 100 fs input pulses centered at λ=6.2 μm with a peak power of 2 kW into the MOF, an optical spectrum as wide as 9.5 μm will be achieved. This spectrum is a suitable source for MIR applications such as spectroscopy, food quality control, and gas sensing.

A key contribution to X-ray dark-field (XDF) contrast is the diffusion of X-rays by sample structures smaller than the imaging system's spatial resolution; this is related to position-dependent small-angle X-ray scattering. However, some experimental XDF techniques have reported that XDF contrast is also generated by resolvable sample edges. Speckle-based X-ray imaging (SBXI) extracts the XDF by analyzing sample-imposed changes to a reference speckle pattern's visibility.

Based on the theory of vector beam, the propagation and tight-focusing models were derived to reveal the focusing and tight-focusing properties of the RP-BG-RPVBs by numerical simulation. Then, the experimental setup was established to validate that the RP-BG-RPVBs presented the fan-shaped and polycyclic intensity distribution, which possessed the features of RP beams, BG beams, and RPVBs, similarly.

Our team has proposed CSI technology with the detection light transparent to the sample to measure the surface topography thus ensuring the numerical aperture of the detection light with high throughput. However, a dedicated optical path to monitor the aberrations caused by the modulation from the sample is necessary and a complex optical path is added for aberration correction, which inevitably increases the design complexity and component costs of the optical system.

Developing damping materials that are both optically transparent and mechanically robust, while offering broad frequency damping capacity, is a significant challenge─particularly for devices that require protection without compromising visual clarity. Conventional methods often either fail to maintain transparency or involve complex designs that are difficult to implement. Here, we present an ionogel system that integrates a physically cross-linked elastic copolymer network with a viscous ionic liquid.

Nature offers unique examples that help humans produce artificial systems which mimic specific functions of living organisms and provide solutions to complex technical problems of the modern world. For example, the development of 3D micro-nanostructures that mimic nocturnal insect eyes (optimized for night vision), emerges as promising technology for detection in IR spectral region. Here, we report a proof of principle concerning the design and laser 3D printing of all ultrastructural details of nocturnal moth Grapholita Funebrana eyes, for potential use as microlens arrays for IR detection systems.
