Abstract

Although 1.3-μm InGaAsP lasers with extrapolated lifetimes in excess of 10⁶ h at 20°C at 5-mW bias are commercially available from a number of different manufacturers, even greater reliability is desired for submarine systems¹ and subscriber loop systems.² For the latter case, a reliability goal of 10⁶ h at 70°C has been proposed.² In addition, improved reliability permits the commercial use of lasers at bias powers of 10-100 mW and creates opportunities for improved performance of optical fiber systems, direct communication with satellites, and other applications of lasers.
