ABSTRACT
Effect of facet coating on the reliability of InGaAlP visible light laser diodes is investigated. Uncoated InGaAlP laser diodes showed facet oxygen related degradation after aging as the gradual degradation mode. Such degradation was drastically suppressed by facet coating. InGaAlP laser diodes with Al2O3-coated facets have operated for more than 2500 h at 50 °C at an optical output power of 3 mW without any significant degradation.
