Improved stability of InGaN-based laser diodes by overcoming facet degradation

Blue-violet emitting laser diodes tend to form SiOx deposits on the facet, causing unstable laser thresholds and beam characteristics. A suited facet coating, together with a hermetically sealed TO can, can avoid this effect and enable complex optical applications.
