CPO laser series part 3: MOPA approach vs Lumentum's single-cavity route
vikramskr · x · 2026-09-08
Part 3 of a series on UHP lasers for co-packaged optics covers the Master Oscillator Power Amplifier (MOPA) approach: Lumentum uses a single high-power cavity producing 400mW+, while Sumitomo boosts a lower-power CW DFB laser with an amplifier. The post weighs tradeoffs and what Lumentum investors should watch.
