Abstract

Commercial viability of the semiconductor lasers imposes several stringent conditions on device fabrication and/or materials: First of all, high yield should be achieved with minimum cost. High long-term reliability is also an extremely important issue for most of applications as the replacement cost of failed devices is prohibitively high, and thus the lifetime of the laser diodes can be a major factor determining the total cost of application systems. In this article, we discuss some of the critical issues related to the commercial viability of semiconductor lasers. As an example of the successful commercialization of the semiconductor lasers developed in research laboratories, we discuss the recent transfer of Al-free laser technology from Northwestern University to Semiconductor Lasers International, Inc. The highly suitable features of Al-free system for industrial scale of production are discussed. The recent results obtained in the industry with low cost and high yield are shown to have high-performance of these Al-free lasers comparable to those observed in the research laboratory.
