Semiconductor lasers have recently been applied to various kinds of optical fiber transmission systems as transmitter sources or pumping sources for optical fiber amplifiers. These lasers have a wide range of characteristics and structures corresponding to the application fields. The most degradation mechanisms, however, originate from their surfaces or interfaces. In this paper, the reliabilities of 0.98 /spl mu/m pumping sources, 1.3 and 1.55 /spl mu/m strained MQW InGaAsP/lnP lasers buried by semi-insulating iron-doped InP, and 1.55 /spl mu/m (strained) InGaAsP/lnP MQW DFB lasers for d-WDM are discussed from the viewpoint of the surface-or interface-related problems.
