Vikram Sekar(@vikramskr):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.
