相关概念： ASIC 专用集成电路HBM 高带宽内存光子学 Photonics
花旗银行TMT团队：“激光器和光纤正被定位为‘下一个HBM（高带宽内存）’。我从2025年就开始谈论像 $LITE / $AAOI 这样的激光器公司，以及向连续波(CW)架构的转变，这领先于当前的行业共识。我完全同意Lightmatter和花旗的观点。仅供参考：激光器方面：$LITE / $SIVE / $AAOI / $COHR / $MTSI / 古河电工 / 住友电工是较知名的标的。光纤方面：$GLW / 古河电工 / 古河光缆 / 住友电工是较知名的敞口（显然供应链中还有更多）。*披露，个人对该主题有持仓。补充评论称：‘紧张的供应状况将支持这些资产的稀缺性溢价。’我们已经看到激光器价格上涨，正如今天在深圳CIOE 2026上看到的 $SIVE 渠道检查以及 $LITE 的财报评论所示。因此，我认为2027-2028年的光子学超级周期将非常类似于2025-2026年的内存周期。尤其是随着高盛修正后的估计显示，每GPU-ASIC的光学内容将显著增加……
Citibank TMT: "lasers and optical fibers are being positioned as the "next HBM." I've been talking about lasers like $LITE / $AAOI since 2025... and architectural shifts toward CW, ahead of the current industry consensus. And fully agree with Lightmatter/Citi. Just for reference: For lasers: $LITE / $SIVE / $AAOI / $COHR / $MTSI / Furukawa / Sumitomo are your better known ones. For fiber: $GLW / Furukawa / Fujikura / Sumitomo are your more well-known exposure (obviously a lot more in the supply chain) *disclosure, personal exposure to theme With added commentary that: "Tight supply conditions will support a scarcity premium for these assets." We're already seeing price hikes with lasers as seen with $SIVE channel checks at CIOE 2026 Shenzhen today + $LITE commentary from earnings. So I think the 2027–2028 photonics supercycle will look a lot like memory did in 2025–2026. Especially as optical content/GPU-ASIC goes up significantly per Goldman Sachs revised estimates...
