Facet stability is ‘hidden lever’ for scalable edge-emitting laser manufacturing

Facet instability creates hidden bottlenecks in edge‑emitting laser manufacturing. This article explores the physics behind facet degradation, the limitations of current surface treatments and ZnSe overgrowth, and how crystalline‑oxide passivation delivers long‑term stability that enables decoupled processing, improved yield, and scalable production.
