Here, we numerically report lasing action from a high-Q cavity in one-dimensional (1D) and two-dimensional (2D) GMR gratings featuring deep grooves. We achieve a high-Q state by adjusting the groove depth to slightly shift the resonance away from the bound states in the continuum, which possess an infinite Q factor. By further aligning the resonance wavelength with the emission band of the gain medium, a nanolaser with a low threshold is achieved. Using a four-level gain system and a finite-difference time-domain approach to simulate the active optical responses, we show that optically pumped lasing with directional beam emission is achieved in a GMR grating coated with an organic gain medium. Additionally, we present groove depth-regulated 2D GMR gratings with high Q factors that are notably polarization-independent. We find that the lasing action is slightly influenced by the polarization angle due to distinct electric field distributions, even though the Q factor remains constant.

The core function is the optical remote manipulation of single and multiple particles, enabling the particles to rotate along the specific optical vortex (OV). The structure of this metalens is based on the Pancharatnam-Berry (PB) phase principle, which constructs a specific phase distribution that results in a vortex electric field distribution in the far field. We investigate the effects of factors such as topological charge numbers, particle radius and refractive index on performance in the single-particle scenario. For the polystyrene (PS) particle with a radius of 300 nm, it can perform a counterclockwise rotation with a radius of about 0.73 μm. The maximum tangential optical force is 54.5 pN, with a maximum torque of 6.98 × 10<sup>−12</sup> m<sup>2</sup>/s, and the radial potential well depth reaches up to 960.4 <em>k</em><sub><em>B</em></sub>T when the topological charge number is 3, resulting in an optimal comprehensive rotational manipulation effect.We also explore scenarios in which multiple particles enter the OV in different manners, comparing the magnitude of optical forces under the same conditions with those of single particle. The input of particles from one side of the OV ensures that the overall manipulation performance is not compromised, with the maximum optical force reaching 109.2 pN. The finding provides a more universal approach to remote control of particles, laying the foundation for more complex and highly integrated far-field particles manipulation and broadening the promising prospects of all-dielectric metalens in the near-infrared wavelength range.</div></div>","PeriodicalId":19586,"journal":{"name":"Optics Communications","volume":"596 ","pages":"Article 132430"},"PeriodicalIF":2.5,"publicationDate":"2025-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145159246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are four sources, each followed by three detectors and arranged equidistant from one another. A switching circuit was implemented using a 555 timer in a stable mode to facilitate the switching of the LED at the aforementioned wavelengths. To acquire data, the rectangular-shaped scanner was kept on a volunteer’s palm and moved towards the tip of the finger. At each position of the imager, red and near-IR radiations were sent through the tissue, and the detectors received backscattered radiation. The current signals obtained from the photodiodes were converted into voltages using a trans-impedance amplifier and read into the computer using Data Acquisition (DAQ) system in twelve parallel channels. Using Beer–Lambert’s law, the attenuation coefficient was calculated and displayed as images. These images show the difference between bony structures and other tissue in the fingers. The distal and proximal phalangeal joints appear lower in intensity than the bony structure of the finger. The oxygen saturation map of the scanned area was also obtained. Subjects with arthritic conditions have inflamed joints. The arthritic joints are sensitive to changes in oxygen saturation. Therefore, the imager could distinguish between normal and inflamed joints and be a screening tool for arthritis.
