The relation between facets and reliability in Fabry-Perot semiconductor lasers is discussed. Surface roconbination centers play important roles in catastrophic optical damage (COD), life problems, electrostatic-discharge-induced degradation. The COD ouurrence level is low in Al-containing materials and high in In-containing materials, compared with GaAs. This is due to the bonding strength of Al with oxygen. Removal of oxygen and defects in the facets and deposition of protective thin films are an effectiv method for the improvement of reliability. Reliability issues of semiconductor lasers in the hard environments such as in the universe are the next problem.
