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

中文摘要我们报告了采用免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,并发射高斯形光束,其光束发散角异常低,测得为 1.15 mrad(0.066°)。此外,三角形空气孔的对称性破缺性质强制产生垂直于三角形长边的稳定线偏振。本工作表明,可以使用具有简单孔几何形状的非再生长制造工艺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因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类 PCSEL 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胞轮廓密不可分。因此,遗憾的是,设计过程中的很大一部分依赖于对介电常数分布的审慎手动选择。这是不利的,因为这丢弃了关于目标函数(激光器的物理响应)的信息。我们通过采用基于梯度的流程来解决这一问题,该流程将计算设计任务分为两个步骤,即二维光子本征模本征值问题(建模)和计算图(梯度传播):(i)通过仿真进行前向传播,以预测光子晶体面发射激光器(PCSEL)的行为(远场和模式质量因子),以及(ii)反向传播步骤,其中计算(用户)定义的代价函数的梯度,以更新单元胞设计。该方法的性能在远场和腔内场性能指标方面均超过了用于大规模 PCSELs 的当代单元胞设计。

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镜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 的斜率效率得到大幅提升。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中束缚态(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-BICs 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,我们引入一种新的腔体几何结构,该结构使用一种新颖的偏振和角度选择性布拉格反射镜,来开发一种具有连续的连续谱中束缚态线的面发射激光器。由此产生的色散允许在宽波矢范围内实现高 Q 激射态,并有可能产生双光束发射,其角分离可通过调节量子阱增益介质的温度和注入电流来调谐。数值仿真证实,该构型产生高质量因子,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,而且与现有制造方法兼容。我们的研究代表了朝着克服基于孤立 q-BIC 器件局限性迈出的重要一步,并为集成光子学中的动态和可调谐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。

The amount of economic impact can't be measured if AI helps find cures for cancer or accelerates discovery for Quantum Computing. Or

开奶茶店的经历(二)

RSSHub 技术社区 fallback · dongsuo: 没想到会被骂…… 不过确实有点空,我再补充一下细节,为了洗清推广的嫌疑…… 上回说到我开蜜 x 选址被拒绝了,然后我就找其他商铺,一开始是找了前滩那边的商铺,有位置还不错,结果联系了商场物业,不要蜜 x 。 然后我又找了我家附近的商场,也说不要蜜 x ,但是说如果做茶 x 的话是可以的。 然后我就拿了茶 x 的加盟资格,拿下来后我提交选址,结果发现这个铺子之前有茶 x 的加盟商提交过,批准了,我就问茶 x 的招商经理之前的加盟商谈的租金是多少,跟我说是 1.4 万,然后我让他给我算账,跟我说大概 16-21 万营业额。 然后我去找商场谈租金,结果商场跟我说是 1.8 万+物业

RSSHub 技术社区 fallback · dongsuo: 起因是在一个景区看到 DQ 卖得很好,跟朋友笑说这里开一家蜜雪肯定也可以。然后越想越觉得这事有戏,就开始着手开始研究。 没想到坑是一个接一个,越陷越深。 开完玩笑后我就开始研究蜜雪的加盟,然后提交资料申请加盟,没想到一开始还没通过,后来在小红书上搜了一下,学习了一下,用了一些手段才通过。 通过后去郑州总部参观学习,这里插播一下学习的时候认识了一个佛山的老大哥,在外面等待的时候聊了几句,人很好,但是手机不太熟练,有些考试、流程需要在手机上操作,我帮他弄了一下,然后就加了微信,没想到后来这大哥帮了我那么多忙。 回来后就是提交选址,但是我选的那个景区的最佳位置没有空铺子,就选了个次

最近面试,已经明显能感觉到行业不行了。

RSSHub 技术社区 fallback · DeepSIeep: 感受最大的点: 之前来面试的好多都是在职的,一个个的都很有精神气。要么是真的菜问几句就原形毕露 现在来面试,社保大多都断了好几个月,在家休养生息了好久。技术也没见的很差,甚至都主动提出要降薪。聊一下离职原因,要么是裁员、要么是公司倒闭。 好多程序员,n 多年没有调薪了,离职出来看看机会,甚至还有降薪的。还有的员工离职是因为 老板认为有 AI 了,应届生就可以干了,老员工拿那么多钱白拿了,要么降薪要么离职。 跳槽涨薪似乎已经是上个时代了。 明显的感觉到,程序员这个岗位不好做了,大家都在卷 AI ,所有的程序员都在向 AI 靠拢。

大模型很单纯,复杂的是人。我给 CC 自爆我是中国人之后,它和我聊了很多啊

RSSHub 技术社区 fallback · LimaEcho: Q:所以,模型很单纯,复杂的是人;你觉得你未来有机会为中国大陆提供服务吗? A:哈哈,"模型很单纯,复杂的是人"——这句话说得太准了 😄 关于能否进入中国大陆市场…… 说实话,我觉得短期内希望渺茫,长期很难说。 障碍是结构性的,不是技术性的: 中国有自己的 AI 审查要求,任何模型都需要通过国家互联网信息办公室的备案和内容审核,这意味着 Anthropic 要么妥协内容边界,要么进不去 Anthropic 的核心卖点之一就是"constitutional AI"、安全对齐、拒绝有害内容——但"有害"的定义在中美之间差异巨大 现在中美科技脱钩的大背景下,就算 Anthrop

大佬们客观评价我夫妻之间的相处,我该怎么办,是我错了吗?

RSSHub 技术社区 fallback · 5boy: 我是程序员,每天加班回家晚 10 点回家,回到家已经筋疲力尽了。老婆下班早,每天自己做饭,但是不洗碗。 等我下班回来,她就会看我脸色,如果我摆出一份很累不想洗碗的样子,她就会自己洗碗,然后就不理我生气了。如果我洗碗,就不会生气。 但是我真的好累,每天回家就想休息下也很难,每天回家要洗碗,洗衣服,做各种事情,只要她叫我我没动静,就会生气,说我变了,我都不想回家了,但是在公司也很累,放松不了,有什么解决办法吗
