Had convo with a CEO working in silicon photonics and lasers yesterday and he referred to Vik’s recent series several times! Give them a read.
(Then I was like “crap I haven’t finished those articles yet” 😅)

Sumitomo has some really interesting high power lasers, but none have made it into ELSFPs as far as I know.
Instead of a single cavity approach like Lumentum, they use a lower-power DFB laser and then an optical amplifier.
The trade-offs they have to make are, well, interesting.
The latest report talks all about it.
