英文原题Size scaling law for radiation losses of modes in photonic crystal surface emitting devices
中文摘要光子晶体表面发射激光器(PCSELs)因其能够产生超高功率和低发散度的激光束而受到广泛关注。这是因为它们支持高功率单模激射,其体积比传统半导体激光器大数个数量级。PCSEL 中有限的横向尺寸是限制其激射模式体积并进而限制其输出功率的主要因素。我们证明,总腔损耗 α = α ⊥ + α ∥ 与器件尺寸 L 之间的缩放关系为:表面辐射损耗按 α ⊥ ∼ O ( L −2 ) 缩放,而边缘辐射损耗 α ∥ ∼ O ( L −3 )。这两个缩放关系都可以由能带图中复频率 ω ( k ) 的二阶展开来解释。我们的结果为设计大面积 PCSEL 类器件时估计尺寸效应提供了指导。
英文摘要Photonic-crystal surface-emitting lasers (PCSELs) have garnered significant attention due to their ability to generate laser beams with ultra-high power and low divergence. This is because they support high-power single-mode lasing with volumes orders of magnitude larger than those of conventional semiconductor lasers. The finite lateral size in a PCSEL is a primary factor limiting its lasing mode volume and, consequently, its output power. We demonstrate that the scaling relation between the total cavity loss α = α ⊥ + α ∥ and the device size L is such that the surface radiation loss scales as α ⊥ ∼ O ( L −2 ), while the edge radiation loss α ∥ ∼ O ( L −3 ). Both scaling relations can be explained by the second-order expansions of the complex frequency ω ( k ) of the band diagram. Our results provide a guideline for estimating the size effect when designing large-area PCSEL-like devices.

英文原题High-Power Terahertz Photonic Crystal Surface-Emitting Laser with High Beam Quality
中文摘要光子晶体表面发射激光器(PCSEL)因具有小远场发散角和高输出功率的优势而受到广泛关注。在这里,我们报道了一种通过优化吸收边界条件并引入对称分布电极而实现的具有高光束质量的高功率太赫兹(THz)光子晶体激光器。实验展示了 3.4 THz 的单模表面发射,最大峰值输出功率为 50 mW。同时,实现了具有 C6 对称性的高度对称远场图案和小发散角。在该器件中,实现了稳定单模运行、高光束质量和高输出功率的集成,这可能对实际应用具有重要意义。
英文摘要The photonic crystal surface-emitting laser (PCSEL) has attracted much attention due to the advantages of a small far-field divergence angle and high output power. Here, we report a high-power terahertz (THz) photonic crystal laser with high beam quality through the optimization of the absorption boundary condition and the introduction of the symmetrically distributed electrodes. Single-mode surface emission at 3.4 THz with the maximum peak output power of 50 mW is demonstrated. Meanwhile, a high symmetric far-field pattern with C6 symmetry and a small divergence angle is achieved. In this device, the integration of the stable single-mode operation, high beam quality and high output power is realized, which may have great significance for practical applications.

英文原题Design of double-lattice GaN-PCSEL based on triangular and circular holes.
中文摘要我们从理论上设计了一种基于三角形和圆形孔的双晶格光子晶体表面发射激光器(PCSEL)。在该设计中,首次提出将多孔 GaN 用作 GaN-PCSEL 的包层,该材料具有较低折射率以及与 GaN 高质量无应力同质外延的特性。研究中采用了有限差分时域(FDTD)、平面波展开(PWE)和严格耦合波分析(RCWA)方法。我们的仿真实现了高达 50 cm -1 的辐射常数和超过 1 W/A 的斜率效率,同时保持较低的阈值增益。我们系统研究了填充因子、刻蚀深度和孔位移对 PCSEL 性能的影响。结果表明,增加填充因子可提高辐射常数和斜率效率。非对称孔图案和不同刻蚀深度具有类似效果。在光子晶体中引入非对称图案和双晶格会打破平面内电场的对称性,而两个孔的不同刻蚀深度会打破垂直方向的对称性。此外,改变双晶格的位移会改变谐振器中的光反馈,从而导致腔损耗和限制因子的变化。
英文摘要We have theoretically designed a double-lattice photonic crystal surface-emitting laser (PCSEL) based on triangular and circular holes. In the design, porous-GaN which has the properties of lower refractive index and high quality stress-free homo-epitaxy with GaN, was first proposed to be the cladding layer for GaN-PCSEL. The finite difference-time domain (FDTD), the plane wave expansion (PWE), and the rigorous coupled-wave analysis (RCWA) method were employed in the investigation. Our simulations achieved a radiation constant of up to 50 cm -1 and a slope efficiency of more than 1 W/A while maintaining a low threshold gain. We conducted a systematic study on the effects of the filling factor, etching depth, and holes shift, on the performance of the PCSEL. The findings indicate that increasing the filling factor improves the radiation constant and slope efficiency. Asymmetric hole patterns and varying etching depths have a similar effect. The introduction of asymmetric patterns and a double lattice in the photonic crystal breaks the symmetry of electric fields in the plane, while different etching depths of the two holes break the symmetry in the vertical direction. Additionally, altering the shift of the double lattice modifies the optical feedback in the resonators, resulting in variations of cavity loss and confinement factor.

英文原题Design of high-slope-efficiency quantum dot photonic crystal surface-emitting lasers with metal reflector
中文摘要我们提出了一种利用金属反射镜的量子点光子晶体表面发射激光器(QD-PCSEL)设计。通过调节 p 包层厚度、引入氧化层并使用 GaInP 作为 p 包层,QD-PCSEL 的斜率效率得到大幅提升。使用三维有限差分时域方法研究了 p 包层厚度和光子晶体(PC)层对斜率效率的影响。仿真结果表明,在填充因子为 22%、PC 层厚度为 420 nm、p 包层厚度为 1.3 μm 时,所设计的 QD-PCSEL 实现了 267 mW/A 的斜率效率。与已报道的实验结果相比,这代表了约 20 倍的提升。
英文摘要We present the design of a quantum dot photonic crystal surface-emitting laser (QD-PCSEL) utilizing a metal reflector. By adjusting the p-cladding layer thickness, incorporating an oxide layer, and using GaInP as the p-cladding layer, the slope efficiency of the QD-PCSEL is greatly enhanced. The influence of the p-cladding layer thickness and the photonic crystal (PC) layer on the slope efficiency was investigated using the three-dimensional finite-difference time-domain method. Simulation results demonstrate that with a fill factor of 22%, a PC layer thickness of 420 nm, and a p-cladding layer thickness of 1.3 μm, the designed QD-PCSEL achieves a slope efficiency of 267 mW/A. This represents an approximately 20-fold improvement compared to reported experimental results.

英文原题Steerable surface emitting laser design based on a line of bound states in the continuum
中文摘要传统光子晶体表面发射激光器(PCSELs)依赖于孤立的准连续谱束缚态(q-BIC),这些态通常位于布里渊区中心,并提供高方向性和高质量因子。然而,由于其所依赖的 q-BIC 具有孤立性质,PCSELs 在需要连续可调性的应用中受到根本限制,需要构建许多不同的 PCSELs 并通过开关切换来实现这种可调性。在这里,我们引入一种新的腔体几何结构,使用一种新型偏振和角度选择性布拉格反射镜来开发一种表面发射激光器,其特征是具有连续的连续谱束缚态线。由此产生的色散允许在宽波矢范围内实现高 Q 激射态,并有可能实现双光束发射,其角间距可通过调节量子阱增益介质中的温度和注入电流来调谐。数值模拟证实,由于其共振态密度降低,该配置产生高质量因子,并支持大面积上的单模运行。该方法不仅将实现连续的角度光束控制,还与现有制造方法兼容。我们的研究代表了克服基于孤立 q-BIC 器件局限性的重要一步,并为集成光子学中动态且可调的光束转向开辟了新的可能性。致谢:SNL 由 NTESS 根据 DOE NNSA 合同 DE-NA0003525 管理和运营。
英文摘要Traditional photonic crystal surface-emitting lasers (PCSELs) rely on isolated quasi-bound states in the continuum (q-BIC) that are generally at the center of the Brillouin zone and which offer high directionality and quality factors. However, due to the isolated nature of the q-BICs they rely on, PCSELs are fundamentally limited in applications that demand continuous tunability, requiring the construction of many different PCSELs that are switched on and off to achieve such tunability. Here, we introduce a new cavity geometry that uses a novel polarization- and angle-selective Bragg reflector to develop a surface emitting laser that features a continuous line of bound states in the continuum. The resulting dispersion allows for high-Q lasing states across a broad wavevector range, with the potential for twin-beam emission whose angular separation can be tuned by adjusting the temperature and injection current into the quantum well gain medium. Numerical simulations confirm that this configuration yields a high-quality factor and supports single-mode operation over large areas due to its reduced density of resonances. The approach will not only enable continuous angular beam control but also offers compatibility with existing fabrication methods. Our study represents a significant step toward overcoming the limitations of isolated-q-BIC-based devices and opens new possibilities for dynamic and tunable beam-steering in integrated photonics.

英文原题Learning light scattering from operator parameter spaces to Galerkin-consistent solution spaces
中文摘要高效且可泛化的全波仿真对于纳米光子学分析和逆向设计至关重要,然而现有方法面临数值求解器计算成本高与神经算子模型对复杂光散射泛化能力有限之间的权衡。在这里,我们提出 FEMONet,这是一个受有限元约束的算子学习框架,可从算子参数空间到 Galerkin 一致解空间学习光散射。算子参数空间编码定义波动方程问题的物理实体,而变分弱形式将该空间与坐标空间和物理解空间联系起来。与算子学习网络集成后,FEMONet 将经典求解器从孤立的问题实例扩展到参数化散射算子。据我们所知,FEMONet 是首个用于复值光散射的 Galerkin 一致算子学习框架,并以控制性矢量波动方程的变分弱形式为基础。有限元离散化将空间导数吸收到组装的刚度矩阵和载荷向量中,从物理损失中移除了神经网络输出的基于坐标的导数,并提高了训练效率。通过预测有限元展开系数而非不受约束的场值,Galerkin 一致公式保留了相容的试探空间和测试空间,在介电、金属、阵列、等离激元和三维纳米光子结构中实现了高精度、稳定训练和泛化。
英文摘要Efficient and generalizable full-wave simulation is essential for nanophotonic analysis and inverse design, yet existing methods face a tradeoff between the high computational cost of numerical solvers and the limited generalizability of neural operator models for complex optical scattering. Here, we introduce FEMONet, a finite-element-constrained operator-learning framework that learns light scattering from an operator parameter space to a Galerkin-consistent solution space. The operator parameter space encodes the physical entities defining a wave-equation problem, while the variational weak form links this space to the coordinate and physical solution spaces. Integrated with operator-learning networks, FEMONet extends classical solvers from isolated problem instances to parameterized scattering operators. To our knowledge, FEMONet represents the first Galerkin-consistent operator-learning framework for complex-valued optical scattering, grounded in the variational weak form of the governing vector wave equations. Finite-element discretization absorbs spatial derivatives into assembled stiffness matrices and load vectors, removing coordinate-based derivatives of the neural-network output from the physics loss and improving training efficiency. By predicting finite-element expansion coefficients rather than unconstrained field values, the Galerkin-consistent formulation preserves compatible trial and test spaces, achieving high accuracy, stable training, and generalization across dielectric, metallic, arrayed, plasmonic, and three-dimensional nanophotonic structures.

昨日/最近交易日的金融分析显示,A股整体偏强,样本平均+0.72%,上证指数+1.12%;创业板指+0.50%;板块上有色最强(+5.11%),半导体相对落后(-1.13%);重点板块中3/7个收涨。 美股整体偏强,样本平均+0.68%,S&P 500 ETF+0.54%;Nasdaq 100 ETF+0.59%;大型科技股中AMD领涨(+4.73%),Super Micro承压(-4.72%)。
昨日走势上,A股大盘样本平均+0.72%,重点板块样本平均+0.70%,市场结构偏向指数权重防守。板块内部强弱分化明显:有色+5.11%居前,半导体-1.13%落后,说明资金并非全面扩散,而是在少数方向里做选择。美股大盘样本平均+0.68%,重点公司样本平均-0.21%,AMD+4.73%强于同组,Super Micro-4.72%拖累风险偏好。
上证指数+1.12%;创业板指+0.50%;板块上有色最强(+5.11%),半导体相对落后(-1.13%);重点板块中3/7个收涨。
后续A股的基准判断是震荡偏强但需要成交和板块扩散确认。大盘指数已表现为整体偏强,样本平均+0.72%,如果强势板块能从有色、银行扩散到消费、银行等低波动方向,反弹持续性会更好;如果仍只有少数题材上涨,则更像结构性轮动。
半导体当前-1.13%,后续要看是否跟随美股AI硬件链修复。AI/算力当前-0.16%,如果Nvidia/AMD/AVGO保持强势,A股映射会更容易延续。银行当前+1.50%,它更像防守和指数稳定器;若银行强、科技弱,市场风格会偏保守。大消费、机器人、有色和光通信需要结合强弱排序看资金轮动,短期更关注能否从单日强势变成连续2-3日相对强势。
S&P 500 ETF+0.54%;Nasdaq 100 ETF+0.59%;大型科技股中AMD领涨(+4.73%),Super Micro承压(-4.72%)。
后续美股的基准判断是风险偏好仍在,但上行动能取决于大型科技股是否继续扩散。指数样本整体偏强,样本平均+0.68%,若AMD、Tesla、TSMC保持强势且VIX不再上行,科技权重仍可能支撑指数;若收益率或美元重新抬升,估值较高的成长股会先承压。
美股重点公司后续主要看三条线:AI硬件链、平台型科技和高波动个股。Nvidia当前+0.16%,它仍是AI风险偏好的核心参照。若AMD、Tesla、TSMC继续领涨,同时Super Micro、ASML、Apple跌幅收敛,指数更容易走出健康轮动;反过来,如果强者补跌,说明资金可能从高估值科技撤出。

RSSHub 技术社区 fallback · Sercheif: 自行车带来的运动量确实比徒步要高,周六 7 点,3 个半钟骑了 52km (和大佬比不上),有上下坡,累的要死,由于周五晚上喝了很多啤酒,所以早上没吃东西,骑到胃痛。 周天城市道路骑行 32km 。再爬个小山( 2 个钟)。 导致这周一周二腿痛,周三恢复,周四小跑 4km 。 这周完全正常吃,甚至吃的比之前多,没想到体重他周五的时候下来了。之前一直稳定在 64-65 之间。 上周的运动情况非常意外。 上面文字输入给大模型后,大模型给得回复: 减脂效果跑步>骑行>徒步。 对于我来说,跑步没办法坚持 3 、4 个钟,做不到一天到晚跑。 骑行可以短时间心率上升,时间持续长,更容易
