英文原题Regrowth-free blue GaN-based photonic crystal surface-emitting lasers with triangular air holes

中文摘要我们报道了采用无再生长方法制备的室温蓝色 GaN 光子晶体面发射激光器(PCSEL)二极管的成功实现。通过采用具有改良三角形空气孔的方形晶格光子晶体结构,我们实现了稳健的二维单模激射。该器件以 5.2 kA/cm2 的阈值电流密度工作,并发射具有高斯形状的光束,其光束发散角极低,测得为 1.15 mrad(0.066°)。此外,三角形空气孔的对称性破缺特性强制形成垂直于三角形长边的稳定线偏振。本工作表明,使用具有简单孔几何形状的非再生长制备工艺可以实现高光束质量的蓝色 PCSEL,为高性能蓝色激光源铺平道路。

英文摘要We report the successful realization of a room-temperature blue GaN photonic crystal surface-emitting laser (PCSEL) diode fabricated using a regrowth-free approach. By employing a square lattice photonic crystal structure with modified triangular air holes, we achieve robust two-dimensional single-mode lasing. The device operates with a threshold current density of 5.2 kA/cm2 and emits a Gaussian-shaped beam with exceptionally low beam divergence, measured at 1.15 mrad (0.066°). Furthermore, the symmetry-breaking nature of the triangular air holes enforces a stable linear polarization perpendicular to the long edge of the triangle. This work demonstrates that high-beam-quality blue PCSELs can be achieved using non-regrowth fabrication processes with simple hole geometry, paving the way for high-performance blue laser sources.

英文原题High-Power Terahertz Photonic Crystal Surface-Emitting Laser with High Beam Quality

中文摘要光子晶体面发射激光器(PCSEL)由于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,我们通过优化吸收边界条件并引入对称分布的电极,报道了一种具有高光束质量的高功率太赫兹(THz)光子晶体激光器。展示了在 3.4 THz 处的单模面发射,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样和小发散角。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Size scaling law for radiation losses of modes in photonic crystal surface emitting devices

中文摘要光子晶体面发射激光器(PCSELs)因其能够产生超高功率和低发散角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 )。这两种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 类器件时估算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Inverse Design of Photonic Crystal Lasers Through Automatic Differentiation Optimization

中文摘要(嵌入式)PhC 谐振腔激光器的行为与单元晶胞轮廓密不可分。因此,设计过程中的很大一部分遗憾地依赖于对介电常数轮廓的审慎人工选择。这是不利的,因为这会丢弃关于目标函数(激光器的物理响应)的信息。我们通过采用基于梯度的方案来弥补这一点,该方案将计算设计任务分为两个步骤,即二维光子本征模式本征值问题(建模)和计算图(梯度传播):(i) 通过仿真进行前向传递,以预测光子晶体面发射激光器(PCSEL)的行为(远场和模式 quality factors);(ii) 反向传播步骤,其中计算(用户)定义的代价函数的梯度以更新单元晶胞设计。该方法的性能在远场和腔内场性能指标上均超过了用于大规模 PCSELs 的当代单元晶胞设计。

英文摘要The behavior of (embedded) PhC resonator lasers is inextricably linked to the unit cell profile. Hence, an overwhelming fraction of the design process unfortunately relies on the judicious manual choice of the permittivity profile. This is disadvantageous for the fact that this throws away information regarding the objective function (the physical response of the laser). We remedy this by employing gradient-based protocols that split the computational design task into two steps—between a 2D eigenvalue problem for the photonic eigenmodes (modeling) and the computational graph (gradient-propagation): (i) a forward passage through the simulation to predict the photonic-crystal surface-emitting laser (PCSEL) behavior (far-field and mode quality factors), and (ii) a backpropagation step where the gradient of a (user) defined cost function is computed to update the unit cell design. The performance of this method exceeds contemporary unit cell designs for large-scale PCSELs in both far-field and intracavity field performance metrics.

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器的量子点光子晶体面发射激光器(QD-PCSEL)设计。通过调节 p 包层厚度、引入氧化物层并使用 GaInP 作为 p 包层,QD-PCSEL 的斜率效率得到显著提升。采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 quality factors。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 并通过开关它们来实现这种可调性。在这里,我们引入了一种新的腔体几何结构,该结构使用一种新型偏振和角度选择性 Bragg 反射器来开发一种具有连续谱中束缚态连续线的面发射激光器。由此产生的色散允许在宽波矢范围内实现高 Q 激射态,并具有双光束发射的潜力,其角度间隔可通过调节温度和注入量子阱增益介质的电流来调谐。数值模拟证实,该配置产生高 quality factor,并由于其降低的共振态密度而支持大面积单模运行。该方法不仅将实现连续的角向光束控制,还与现有制备方法兼容。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谐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.

市场复盘 · 最近交易日 A股 2026-06-18 / 美股 2026-06-18 / 宏观 2026-06-17

昨日/最近交易日的金融分析显示,A股整体偏强,样本平均+1.32%,上证指数-0.43%;创业板指+2.05%;板块上AI / 算力最强(+5.03%),银行相对落后(-2.42%);重点板块中5/7个收涨。 美股整体偏强,样本平均+1.41%,S&P 500 ETF+1.04%;Nasdaq 100 ETF+2.51%;大型科技股中Super Micro领涨(+10.37%),Microsoft承压(+0.13%);10Y美债收益率+1.35%。

走势总结

昨日走势上,A股大盘样本平均+1.32%,重点板块样本平均+1.62%,市场结构偏向题材/行业线索。板块内部强弱分化明显:AI / 算力+5.03%居前,银行-2.42%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+1.41%,重点公司样本平均+3.40%,Super Micro+10.37%强于同组,Microsoft+0.13%拖累风险偏好。

后续趋势研判

  • 基准情景:A股维持结构性轮动,美股科技权重保持分化但不系统性下跌;这种情况下日报后续应重点跟踪半导体、AI/算力、光通信和Nvidia/AVGO/AMD的联动。
  • 偏强情景:VIX回落、美元或10Y美债不再上行,且A股强势板块扩散到消费/银行等方向;这会提高指数级反弹的可信度。
  • 偏弱情景:波动率上行、美元走强、10Y 美债收益率上行,同时美股AI龙头走弱;这会压制A股科技映射,市场可能回到防守轮动。

A股市场

A股复盘

上证指数-0.43%;创业板指+2.05%;板块上AI / 算力最强(+5.03%),银行相对落后(-2.42%);重点板块中5/7个收涨。

后续趋势研判

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+1.32%,如果强势板块能从AI / 算力、半导体扩散到消费、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+3.94%,后续要看是否跟随美股AI硬件链修复。AI/算力当前+5.03%,如果Nvidia/AMD/AVGO保持强势,A股映射会更容易延续。银行当前-2.42%,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。

后续趋势研判

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+1.41%,若Super Micro、TSMC、AMD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+2.95%,它仍是AI风险偏好的核心参照。若Super Micro、TSMC、AMD继续领涨,同时Microsoft、Apple、Tesla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。

  • 美股AI硬件链样本平均+4.17%,A股AI/算力+5.03%、半导体+3.94%,可作为跨市场科技风险偏好的参照。

@aleabitoreddit | public X mirror | opinion/NFA | no login/cookies

Serenity original-post candidate from public X mirror (opinion/NFA): I mean... if i had to guess, $LPK did claim "80% of customers among major global players have selected LPKF equipment".

@aleabitoreddit | public X mirror | opinion/NFA | no login/cookies

Serenity original-post candidate from public X mirror (opinion/NFA): Trendforce reports that $AMD is actively trying to secure CW laser supply with multiple major procurement orders...

一个 reCAPTCHA 把我骗到重装系统,分享出来给大家提个醒

RSSHub 技术社区 fallback · Genieliu111: 昨天想查一下今天龙舟赛的安排,就用 DuckDuckGo 快速搜了一下,点进一个网站。https://hkcdba.org/hkidbr (后面查又说是官方网站,是被黑了吗?) 打开之后,弹出了标准的 "I'm not a robot" reCAPTCHA 验证。我很自然地就准备开始点图片验证,结果这次等来的压根不是图片,而是直接弹出了一张指引图,一步一步教我怎么打开终端,粘贴进去运行。应该是在我点击验证的时候,就已经把那段命令自动复制到我的剪贴板了。我当时也没多想,平时 github 里粘贴命令运行已经形成肌肉记忆了,鬼使神差地打开终端,直接粘贴,按下了回车。 运行

前端界面比想象中复杂好多

RSSHub 技术社区 fallback · weiyunjun: 刚接触 Vibe Coding 时就感觉前端比后端复杂好多,后端只需要不停按照需求优化性能就好了,有客观的测试数据,如果优化效果不符合预期就检查架构是否有改进的空间。总而言之就是流程可控。 前端界面一开始完全不会,找类似软件学习,然后和 Codex 描述需求,各种细节瑕疵,花费很大精力改得差不多,身心俱疲,然后下一次改动又重复一遍这个流程。 痛定思痛,反思流程问题,于是整理出前端文档,找 ChatGPT 网页端生成组件和布局的示意图,包含各种状态。再让 Codex 根据示意图和文档绘制界面,再修改文档修复 bug ,改完以后找 ChatGPT 重新生成最新版本的示意图。

端午节快乐!求推荐高质量 VPS 线路

RSSHub 技术社区 fallback · wdv2ly: 楼主联通宽带,以前用过几年 dmit ,稳定性可以,速度感觉一般。后来蹬了一年 clawcloud ,速度起飞,稳定性拉胯到底,这个月底要跑路了,得赶紧换一家,不想折腾了, 预算 3K 每年,如果特别好也可以酌情加一些。机器要稳定(速度,可访问性,ip 质量等各方面),位置最好是新加坡(现在 ip 所在地,怕突然换地区 cc 之类的被风控),次选香港日本等。 可以接受推广链接,但希望对得起前面的标准,谢谢各位~
