Semiconductor laser diodes: applications, trends and their technological challenges — •Werner Bergbauer, Andre Somers, Teresa Wurm, Matthias Peter, Christoph Eichler, Sven Gerhard, Georg Bruederl, Soenke Tautz, Bernhard Stojetz, Andreas Loeffler, Martin Mueller, Harald Koenig, and Uwe Strauss — OSRAM Opto Semiconductors GmbH, Leibnizstr. 4, 93055 Regensburg, Germany

The variety of applications using semiconductor lasers is strongly increasing. Especially the tremendous performance increase over the past years is enabling new designs. For example, nitride based laser diodes are used for augmented reality and business projection as well as for phosphor based automotive headlamps. Thus both, efficient low power single mode as well as high power multi-mode lasers, have to be addressed in development and production. In parallel, applications like gesture recognition and autonomous driving powered by infrared lasers based on the arsenide material system will strongly increase. Next to the performance, reliability and finally the cost reduction of the devices are key factors for success. During the presentation we will discuss the current status, actual technological challenges and future perspectives for laser diodes.
