FIGURE 1. Passivation-enabled process decoupling in laser diode manufacturing. Cleaving in air is decoupled from passivation, and passivation decouples mirror coatings. Both safe windows reduce time pressure while maintaining oxidation-inert facets, which enables predictable downstream coatings, burn-in, and final test.
