ABSTRACT

Abstract

Traditionally semiconductor lasers have been used as miniature and efficient light sources for applications ranging from powering optical networks to reading DVDs. For such applications, performance depends critically upon optical cavity design. This talk will review the three fundamentally different structures used to engineer the confinement of light in semiconductor lasers. For the simplest of these structures, we present a series of experiments that show how reliability is intrinsic to device design.

Emerging technologies see semiconductor lasers becoming functional devices, used for all-optical switching, logic and memory, as opposed to mere light sources. We present experiments that demonstrate the ultrafast all-optical access and control of light to perform these tasks, even with commercial lasers readily available today.

Finally, we will identify target areas of research that require significant investigation to realize emerging applications. These target areas all stem from our poor understanding of how light behaves, even in the most rudimentary passive optical structures.
