Due to the inherent unevenness of grinding wheels and abrasives, surface defects inevitably persist on precision fused silica optics. Recently, the non-contact, non-destructive CO₂ laser processing of fused silica begins to attract research attentions. Through the spontaneous micro-flow of the molten materials, the fused silica surface can be smoothed and the defects can be healed without mass loss. However, the micro-flow and material rearrangement in the defect area under laser irradiation involves complex physical interactions such as laser energy deposition, heat transfer, fluid dynamics, and volumetric strain. The contribution mechanisms to the morphological evolution remain unclear, preventing precise control of defects and the achievement of high-quality surfaces. In this work, a new numerical model coupling volume strain with the traditional heat transfer and micro-flow models is established. The computational model shows a high degree of consistency with the experimental results, with a deviation of less than 5%. The contribution of various thermo-mechanical effects, including surface tension, Marangoni force and thermal modification, to the evolution of surface morphology during the defect healing process was revealed. It is found that, the surface tension and thermal strain are the primary factors dominating the surface deformation. Both calculated and experimental results demonstrated that, surface tension is the dominant contributor to the defect healing behavior, with the contribution of the other forces to the defect morphology being less than 1% of that of surface tension. This work can provide guidance for the regulation of the defect healing and other laser processing procedures of fused silica optics.</div></div>","PeriodicalId":19511,"journal":{"name":"Optics and Laser Technology","volume":"188 ","pages":"Article 113013"},"PeriodicalIF":4.6,"publicationDate":"2025-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143850681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

One common technique employed in QKD is polarization encoding. However, silicon materials lack the electro-optic (EO) effect, whereas lithium niobate materials possess this property. In this paper, we propose a polarization encoding structure based on thin-film lithium niobate (TFLN) modulators and silicon-on-insulator (SOI) two-dimensional (2D) grating coupler for 1550 nm wavelength QKD systems. The chip integrates two lithium niobate push–pull intensity modulators, two phase modulators, and a fiber array coupled with a silicon-based 2D grating coupler. The combination of the excellent EO properties of lithium niobate and the high-density integration of the SOI platform enables high-performance polarization state preparation for quantum communication. We present polarization state modulation by adjusting the thermo-optic modulator (TOM) and electro-optic modulator (EOM) using precise direct current (DC) and high-frequency signals.

However, current infrared detectors have low resolution, and improving resolution from the hardware perspective is expensive. To address issues such as low resolution and significant loss of high-frequency information in infrared images, this study introduces a lightweight neural network model. Compared to existing super-resolution models, the proposed model exhibits lower complexity and is convenient for edge deployment, enabling real-time processing which extends the application scope of infrared imaging. This approach employs a novel architecture specially designed for the characteristics of infrared data, which significantly enhances the image clarity with a minimal increase in parameters, thereby making it suitable for resource-constrained real-time applications. Specifically, we design a lightweight multi-scale feature extraction module that utilizes group convolutions with varying kernel sizes across groups to realize efficient feature extraction. In addition, we introduce a multi-scale feature fusion module that adaptively integrates features harvested from preceding layers. To enhance the network’s ability to learn high-frequency information, we added a Fourier transform branch to the network and incorporated a frequency loss function into the loss function.
