IT之家 2 月 28 日消息，科技媒体 Wccftech 昨日（2 月 27 日）发布博文，报道称联发科进军硅光子技术领域，通过子公司斥资约 9000 万美元（IT之家注： 现汇率约合 6.18 亿元人民币）入股硅光子初创公司 Ayar Labs。 联发科通过其子公司 Digimoc Holdings Limited，向硅光子初创公司 Ayar Labs 投资了约 9000 万美元，借此交易获得了 172 万股特别股，占据 Ayar Labs 约 2.4% 的股份。 该媒体解读认为，英伟达、英特尔和 AMD 此前均已参股该公司，联发科此次入局显然意在硅光子技术逐渐成熟之际，为自己争取到下一代芯片制造领域的 关键话语权。 通过部署光学链路，I/O 功耗最高可以降低 80%，同时为边缘 AI 和即将到来的 6G 蜂窝网络解锁更高的数据吞吐量。此外，硅光子技术还可应用于共封装 光学（CPO）领域，将光学引擎直接集成在 SoC 封装内，从而缩短电气走线并减少延迟与发热。 由于光信号的传输速度远超电信号，且几乎不产生热量，这项技术在数据包传输时能实现更高的带宽、更低的延迟以及显著降低的能耗。 Ayar Labs 专门 ...

划重点 ① 2026 年，全球算力基建正式跨入"连接为王"的通信大年。当 AI 集群规模冲向更大级别，1.6T 速率让传统铜缆因电阻热效应撞上物理天花 板，光电转换从备选项跃升为唯一解。这场由大模型迭代倒逼出的"光速互联"革命，正开启一场比 2000 年光纤时代更具实力的价值重估。 ② LITE 靠垂直整合实现从"零件差价"到"系统溢价"的跨越；COHR 通过精简业务、聚焦核心资产以收割 AI 最肥美的利润；黑马 AAOI 则凭 借 LPO 方案的成本优势与微软深度绑定，展现极高弹性。硅光子、CPO 与 LPO 三线并进，核心目标只有一个：消灭能耗与延迟，重塑 1.6T 时代的定价权。 ③ 不同于 2000 年的供给泡沫，2026 年是需求倒逼下的刚需基建。虽然估值波动与技术更迭仍是变量，但投资逻辑已发生质变：核心不再是算 力多强，而是连接能效多高。拥有芯片自研能力与巨头订单的厂商，正接过 GPU 的火炬，点亮 AI 时代的下半场红利。 站在 2026 年来看，全球算力基建的叙事正发生一场深刻的权力交接。如果说 2024 至 2025 年是属于英伟达和芯片代工厂的"GPU 盛世"，那么 2026 年则 正式开 ...

来源：半导体行业观察 周四，Tower Semiconductor 的股价再次飙升，推动这家以色列芯片制造商的市值突破 150 亿美元。 此举标志着Tower公司估值的一次显著提升：其市值如今约为英特尔两年前放弃收购前承诺支付的50亿 美元价格的三倍。当时，由于监管机构未能批准，英特尔最终放弃了收购计划。那时，交易的失败被普 遍视为Tower公司的一次挫折。而如今，这越来越像是一个转折点。 过去六个月，Tower的股价上涨超过160%，其中今年更是大幅上涨，使其估值倍数甚至超过了英伟达。 这波涨势使Tower从一家长期被忽视的专业芯片制造商，一跃成为人工智能基础设施建设中最受瞩目的 受益者之一。 对于Tower公司首席执行官Russell Ellwanger来说，这种转变不仅体现在交易屏幕上，也体现在生产车 间。"我晚上回家，我的家人，甚至邻居，都会跟我谈论Tower的股票，"他上个月在接受Calcalist采访时 说。"他们觉得我有点特别。" 这种前景有助于解释市场的热情。即便在新增产能投入使用之前，Tower公司已预测第四季度营收将创 下4.4亿美元的纪录，并预计2025年全年营收将达到15亿美元，同比增 ...
