英文原题Laterally coupled photonic crystal surface emitting laser arrays

中文摘要我们提出并研究了一种基于横向耦合光子晶体表面发射激光器(PCSELs)的新型相干激光器阵列设计。作为一种新型半导体激光技术,PCSELs 在平面腔中具有场限制,并在表面法线方向发射激光束。通过采用异质结构光子晶体设计来工程化 PCSELs 之间的横向耦合,我们可以实现 PCSELs 阵列的相干运行。在本文中,我们展示了一种被动耦合 PCSEL 阵列设计的相干运行。我们在目标波长为 1040 nm 的 GaAs 基量子阱异质结构上制备了 PCSEL 阵列器件。实验结果表明,2×2 PCSEL 阵列的光谱线宽为 0.14–0.22 nm。通过自干涉实验表征了光束合成性能。观察到 PCSEL 阵列与单个 PCSEL 器件之间相似的相干性。我们通过被动横向耦合实现的紧凑 PCSEL 阵列设计在片上光子计算、量子和信息处理领域具有潜在应用。

英文摘要We propose and investigate a novel coherent laser array design based on laterally coupled photonic crystal surface-emitting lasers (PCSELs). As a new type of semiconductor laser technology, PCSELs have field confinement in a planar cavity and laser beam emission in the surface normal direction. By engineering lateral couplings between PCSELs with heterostructure photonic crystal designs, we can achieve coherent operations from an array of PCSELs. In this paper, we demonstrate coherent operation from a passively coupled PCSEL array design. We fabricated PCSEL array devices on a GaAs-based quantum well heterostructure at a target wavelength of 1040 nm. Experimental results show that the 2-by-2 PCSEL arrays have spectral linewidth of 0.14–0.22 nm. Beam combining performance was characterized by self-interference experiments. Similar coherency between the PCSEL array and single PCSEL device was observed. Our compact PCSEL array designs by passive lateral coupling have potential applications in fields of on-chip photonic computing, quantum, and information processing.

市场复盘 · 最近交易日 A股 2026-06-03 / 美股 2026-06-02 / 宏观 2026-06-02

昨日/最近交易日的金融分析显示,A股整体偏强,样本平均+1.04%,上证指数+0.22%;创业板指+1.65%;板块上光通信最强(+4.01%),大消费相对落后(-1.47%);重点板块中5/7个收涨。 美股整体偏强,样本平均+0.51%,S&P 500 ETF+0.14%;Nasdaq 100 ETF+0.46%;大型科技股中Super Micro领涨(+7.02%),Microsoft承压(-4.17%);VIX-1.64%。

走势总结

昨日走势上,A股大盘样本平均+1.04%,重点板块样本平均+1.39%,市场结构偏向题材/行业线索。板块内部强弱分化明显:光通信+4.01%居前,大消费-1.47%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+0.51%,重点公司样本平均+1.19%,Super Micro+7.02%强于同组,Microsoft-4.17%拖累风险偏好。宏观风险代理方面,VIXY 波动率ETF-1.64%、美元指数+0.12%,这会影响后续科技成长和周期资源方向的弹性。

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+1.04%,如果强势板块能从光通信、AI / 算力扩散到消费、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。

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+0.51%,若Super Micro、ASML、Broadcom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。

半导体当前+3.37%,后续要看是否跟随美股AI硬件链修复。AI/算力当前+3.45%,如果Nvidia/AMD/AVGO保持强势,A股映射会更容易延续。银行当前-0.89%,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。

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-0.69%,它仍是AI风险偏好的核心参照。若Super Micro、ASML、Broadcom继续领涨,同时Microsoft、Alphabet、Amazon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。

  • 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:VIXY 波动率ETF继续上行、美元指数走强、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股复盘

上证指数+0.22%;创业板指+1.65%;板块上光通信最强(+4.01%),大消费相对落后(-1.47%);重点板块中5/7个收涨。
