我认为超大规模云计算厂商尚未意识到其中的危险。$COHR 是领先的“近乎垂直整合”的美国公司。但风险在于，它仍受制于磷化铟(InP)原料的瓶颈，并从现货市场购买6N级磷化铟多晶（原料）。 如果上述公司停止销售6N多晶，Coherent 的激光和收发器业务将随着超大规模云计算厂商的建设而有效受阻。 Coherent 并不拥有像 Vital Materials 或 $AXTI 那样规模的主要铟矿或大规模6N合成工厂。 简单来说：Coherent 是打破住友与 $AXTI 之间衬底双寡头垄断的“西方希望”，但他们目前却是磷化铟原料垄断的人质。
Don’t think hyperscalers understand the danger yet. $COHR is the leading “virtually integrated” American company. But the risk is it’s still stuck in the bottleneck for InP feedstock and buys 6N InP polycrystal (feedstock) from the merchant market. If the companies above stop selling 6N polycrystal, Coherent’s laser and transceiver business effectively hits a wall alongside the hyperscaler buildout. Coherent does not own major Indium mines or high-volume 6N synthesis plants on the scale of Vital Materials or $AXTI. To put it more simply: Coherent is the "Western Hope" for breaking the substrate duopoly between Sumitomo and $AXTI, but they are currently a hostage to the InP feedstok monopoly.
