$COHR 表现惊人，凭借其新建的 6 英寸晶圆厂，可能是磷化铟(InP)衬底生产领域的美国领先企业。 两个细微差别： 1. 他们的产量远未达到超大规模数据中心(Hyperscalers)所需的规模，目前 $AXTI 和住友(Sumitomo)的产出量更大。 2. 他们受限于上游生长晶体所需的 InP 原料（由 Vital、$DOWA 和 $AXTI（自产）控制）。 CEO 在投资者关系(ER)会议中表示，其产能已满载，且受限于 InP 激光器（以及生产它们所需的上游一级 InP）。 我的思考过程是，超大规模数据中心可能不会继续向 $COHR 增加订单积压，而是向上游延伸。他们会直接从 Vital、$DOWA、$AXTI 等控制 InP 的企业采购 6n-7n 纯度原料，交给住友/$COHR 等晶圆厂，或者再高一级，直接收购 InP 衬底库存 -> 交给 $LITE 作为保险。 话虽如此，大量资金可能会注入西方供应链，但由于上游瓶颈，其产能仍远远不够。
$COHR is amazing and probably the leading US company for InP substrate prod with their new 6in wafer fab. Two nuances: 1. Their production is nowhere close to the scale needed for hyperscalers that $AXTI and Sumitomo currently outputs 2. They are bottlenecked by upstream InP feedstock needed to grow crystals (owned by Vital, $DOWA, and $AXTI (captive)). CEO said in their ER that their capacity was maxed out and limited by InP lasers (and by 1 hop InP needed to produce them) My thought process is that instead of placing more order backlogs with $COHR, hyperscalers would go upstream. They would directly source 6n-7n from Vital, $DOWA, $AXTI and others that control InP, and give them to fabs like Sumitomo / $COHR or one level higher, buy out stock of InP substrates -> hand to $LITE as insurance. That being said a lot of money will likely be poured into Western supply chains but their capacity is nowhere enough since they're still bottlenecked upstream.
