The novel waveguide structure utilizes a tilted mirror and a non-closed whispering gallery mode to suppress F‑P resonance. Furthermore, based on the material characteristics of the mid-infrared InGaAs/InAlAs quantum cascades (QC), we investigate the effects of the parameters of the dual tilted waveguide structure on the optical properties, such as the waveguide width, tilted angle, span-to-depth ratio, and heat dissipation spacing. We theoretically obtain a device with low reflectivity, low optical loss and good heat dissipation effect. Finally, we demonstrate the output characteristics of the device by simulation, and the results show that the novel waveguide structure can realize the output of one-side superluminescence light. The central wavelength of the device is ∼10 µm, and the spectrum of the full-width half-maximum is ∼2 THz. The device has directional output properties, with a parallel far-field divergence angle of ∼37.5°. This novel dual tilted waveguide structure shows a great potential in achieving the high power and wide spectral output of SLED.</p></div>","PeriodicalId":663,"journal":{"name":"Journal of Russian Laser Research","volume":"45 6","pages":"611 - 618"},"PeriodicalIF":0.8,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147686592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Here the filter is used as the polarization-dependent element to induce the polarization hole burning (PHB) effect. By adjusting the polarization controllers (PCs), the wavelength interval and number of output wavelengths can be changed. The output wavelengths can be switched from single-wavelength to eight wavelengths. Additionally, dual, three, four, five, six, seven, and eight wavelengths with wavelength intervals can be obtained. The MPM filter is placed in the temperature control box, and the single wavelength tuning can be realized by changing the temperature, and the tuning range is from 1528.73 to 1562.17 nm.

In this paper, we examine the distribution characteristics of the orbital angular momentum of Laguerre–Gaussian (LG) vortex beams in atmospheric and oceanic turbulence, derive analytical expressions for the spiral spectrum of LG vortex beams, and analyze the effects of the wavelengths, transmission paths, and beam intensity on the spectrum within turbulent environments. The findings show that long-wavelength LG vortex beams perform better in turbulent conditions. Blue-green LG vortex beams exhibit significantly enhanced performance in downlink atmospheric transmission compared to uplink transmission. Additionally, greater intensities of atmospheric and oceanic turbulence lead to a more pronounced extension of the spiral spectrum. Oceanic turbulence exerts a greater influence on blue-green LG vortex beams compared to atmospheric turbulence. This paper presents the theoretical foundation for accomplishing two-way blue-green LG vortex beam transmission between the ocean and the atmosphere.</p></div>","PeriodicalId":663,"journal":{"name":"Journal of Russian Laser Research","volume":"45 6","pages":"664 - 675"},"PeriodicalIF":0.8,"publicationDate":"2026-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147686598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

But they usually depend on one modality and cannot extract information from others. LiDAR and camera multimodal fusion combines data from two sources, greatly increasing detection precision. This paper proposes a new network called the Convergent Attention-Enhanced Camera-LiDAR Object Candidates System (CAECs). It is a decision-level fusion architecture for target detection. First, the CAECs network uses an advanced candidate encoding mechanism. This mechanism sifts through and saves prime candidates from both 2D and 3D detectors. It forms a comprehensive feature tensor and avoids missing crucial detections. Second, we use AgileSightNet to improve feature relevance and strengthen important data. AgileSightNet includes layered channel fusion and an attention scheme. The tests on the KITTI benchmark show that our method performs better at detecting pedestrians and cyclists. It improves accuracy by 6.43% and 6.26% compared to the existing 3D multimodal networks. Compared to single-modal 3D networks, our method improves detection accuracy by 13.03% and 5.97%.
