In the rapidly evolving field of nanotechnology, the ability to manipulate microscopic particles with precision at far-field distances remains a challenging endeavor. This paper introduces a dynamically tunable optical vortex based on elliptical gold nano-antenna arrays, enabling real-time control over the focal point position of optical vortex. By allowing wavelength-dependent precise adjustments of focal point positions over a range of several micrometers, our method significantly enhances particle manipulation capabilities, compared with traditional static plasmonic tweezers. We demonstrate the generation of far-field optical vortices, achieving effective trapping of nanoparticles with a dynamically tunable trapping distance up to around 14.7 μm from the metasurface, well beyond the near-field limit in conventional plasmonic tweezers. This advancement addresses limitations associated with conventional plasmonic manipulation, such as detrimental thermal effects and confinement to the near-field region. Besides representing a significant progression in nanoparticle manipulation techniques, this innovative platform opens new avenues for applications in optical micro-robotics and advanced material structuring, propelling the field forward and inviting further exploration of tunable optical forces.

We evaluated the microstructural and thermal stability of beef fat and lean meat tissue over 56 days of household frozen storage ($-18,^{circ} mathrm{C}$) using Brillouin spectroscopy, Raman spectroscopy, Differential Scanning Calorimetry (DSC), and Fluorescence Lifetime Imaging Microscopy (FLIM). Mechanical stiffness represented by Brillouin shift values ($Delta nu$) and Brillouin line FWHM values ($Gamma$), and thermal metrics ($Delta H$, $T_{m}$) of fat and lean meat samples remained within experimental uncertainty ($pm text{0.2},text{GHz}$; $p>0.05$) throughout storage. While Raman spectra showed minimal chemical contrast between tissue types, autofluorescence lifetime constants ($tau _{1}$, $tau _{2}$) and Brillouin shifts enabled robust, label-free mechanical discrimination of fat versus lean meat domains. Compression and acetone treatments confirmed the techniques’ sensitivity. These results demonstrate that common home-freezing preserves beef tissue microstructure and fat thermal behavior over two months, and that combined optical and calorimetric methods offer a non-destructive framework for meat quality assessment.

We report the development of InAs/InAlGaAs quantum-dot (QD) lasers grown on both InP and Si substrates. A modified indium flush technique was employed to control dot-height distribution and tailor the emission wavelength by using a strained partial capping layer. Using this approach, 7-stack InAs/InAlGaAs QD lasers on InP substrates exhibit a low threshold current density (Jth) of 63 A/cm2 per QD layer and high-temperature operation up to 140 °C. Furthermore, electrically pumped InAs/InAlGaAs QD lasers directly grown on Si are also demonstrated, with a low Jth of 1.35 kA/cm2 and a maximum operating temperature of 100 °C. This work highlights the effectiveness of the modified indium flush in achieving high-performance InAs/InAlGaAs QD lasers. These results represent a significant step forward in the development of high-performance C-/L-band QD lasers in the InAs/InAlGaAs/InP material system for Si photonics.
我们报道了在InP和Si衬底上生长的InAs/InAlGaAs量子点（QD）激光器的发展。采用一种改进的铟冲光技术，利用应变的部分覆盖层来控制点高分布和定制发射波长。使用这种方法，在InP衬底上的7层InAs/InAlGaAs QD激光器表现出每QD层63 a /cm2的低阈值电流密度（Jth）和高达140°C的高温工作。此外，还演示了直接在Si上生长的电泵浦InAs/InAlGaAs QD激光器，其Jth低至1.35 kA/cm2，最高工作温度为100°C。这项工作强调了改性铟在实现高性能InAs/InAlGaAs QD激光器中的有效性。这些结果代表了在硅光子学InAs/InAlGaAs/InP材料体系中高性能C / l波段QD激光器的发展向前迈出了重要的一步。
