- I use CIG for read through on Western markets, since they disclosed 5 CW laser supply agreements. But I remember likely $MSFT and $CSCO were optical customers. Some of the more interesting companies were Nanjing Casela / 南京镭芯光电 (private) and Suzhou Dingxin / 苏州鼎芯光电 (private, but has a public parent via Yongding) for their potential CW laser sources. But even after that, their filings showed they plan to stockpile CW lasers for next few years to avoid future bottlenecks. I don't know enough about Cambridge fundamentals to comment on how well they might perform in the future.
Ongoing takes on other optical names too
