Abstract
Visible III-nitride laser diodes (LDs) are key components for a variety of applications, including high-definition data storage systems, projectors, and displays. Device performance has been accelerated by the recent development of III-nitride LDs on nonpolar and semipolar crystal orientations, which provide a variety of beneficial characteristics. In this chapter we first introduce the fundamentals of III-nitride materials, including polarization effects and nonpolar and semipolar orientations. We then discuss optical properties, materials issues, and waveguide design for nonpolar and semipolar LDs. A brief description of applications for III-nitride LDs is also included, followed by a discussion of fabrication techniques. We then present a history of results and show LDs with state-of-the-art performance on nonpolar and semipolar orientations. Finally, future directions and information on additional reference materials are provided.
