“…3.2.3, the time to COD can be estimated to be more than 10 5 hours under a constant output power less than 80-100 mW. The NEC group reported that the lifetime limited by COD is more than 10 5 hours under a constant output power operation of around 100 mW at 25°C, 43 although the COD level has to be considered with the optical power density at the facet. During operation under a higher output power (density), the lasers fail suddenly when COD occurs (as shown in Fig.…”

The degradation behavior and the reliability of 980 nm lasers and 1480 nm lasers are reviewed and discussed. In addition, packaging problems for the high power lasers are also discussed from the application viewpoint. For 980 nm lasers the reliability in laser chip is limited mainly by the instability of an interface between the laser material (facet) and the anti-reflecting coating film, and for most 1480 nm lasers the reliability of the laser chip is determined mainly by the instability of a buried heterointerface. These reliability problems have been solved, however, by examining the material properties and improving device fabrication technology. The main packaging problem is a packaginginduced failure (PIF) causing sudden failure in 980 nm lasers sealed in dry N2 or Ar, but packaging problems have also been suppressed or eliminated. The device technology and packaging technology needed to make high power pump laser modules have been established, and erbium-doped fiber amplifiers pumped by these lasers are indispensable components of many optical transmission systems. 55 Current Trends in Optical Amplifiers and Their Applications Downloaded from www.worldscientific.com by UNIVERSITY OF BIRMINGHAM LIBRARY -INFORMATION SERVICES on 03/21/15.
