This book was released on 1992 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among potential applications of wide-gap II-VI compound semiconductor quantum wells (QW) and superlattices at short visible wavelengths are lasers and nonlinear optical devices. Substantial progress has been recently made with ZnSe-based heterostructures; in particular (Zn, Cd)Se/ZnSe QW's have shown pulsed room temperature laser action in optical pumping experiments in both multiple and single well structures. At the same time, these QW's have also been found to display strong excitonic absorption features (a> 10(5) cm-1), which are well preserved up to room temperature and beyond. This raises the question about the origin of the gain for lasers, that is, the role of Coulomb effects when compared to the usual inversion from an electron-hole plasma encountered e.g. in GaAs quantum well lasers. Here we show initial results of pump-probe experiments and laser studies which indicate the presence of excitonic gain up to temperatures at least as high as 200 K. Moreover, with increasing pair density, the gain evolves directly from saturation of the excitonic gain in the (Zn, Cd)Se/ZnSe quantum wells.

Download or read book Quantum Confined Laser Devices written by Peter Blood and published by Oxford University Press. This book was released on 2015 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: The semiconductor laser, invented over 50 years ago, has had an enormous impact on the digital technologies that now dominate so many applications in business, commerce and the home. The laser is used in all types of optical fibre communication networks that enable the operation of the internet, e-mail, voice and skype transmission. Approximately one billion are produced each year for a market valued at around $5 billion. Nearly all semiconductor lasers now use extremely thin layers of light emitting materials (quantum well lasers). Increasingly smaller nanostructures are used in the form of quantum dots. The impact of the semiconductor laser is surprising in the light of the complexity of the physical processes that determine the operation of every device. This text takes the reader from the fundamental optical gain and carrier recombination processes in quantum wells and quantum dots, through descriptions of common device structures to an understanding of their operating characteristics. It has a consistent treatment of both quantum dot and quantum well structures taking full account of their dimensionality, which provides the reader with a complete account of contemporary quantum confined laser diodes. It includes plenty of illustrations from both model calculations and experimental observations. There are numerous exercises, many designed to give a feel for values of key parameters and experience obtaining quantitative results from equations. Some challenging concepts, previously the subject matter of research monographs, are treated here at this level for the first time.

Available in PDF, EPUB and Kindle. Book excerpt: Wide-band-gap semiconductors have been a research topic for many decades. However, it is only in recent years that the promise for technological applications came to be realized; simultaneously an upsurge of experimental and theoretical activity in the field has been witnessed. Semiconductors with wide band gaps exhibit unique electronic and optical properties. Their low intrinsic carrier concentrations and high breakdown voltage allow high-temperature and high-power applications (diamond, SiC etc.). The short wavelength of band-to-band transitions allows emission in the green, blue, or even UV region of the spectrum (ZnSe, GaN, etc.). In addition, many of these materials have favorable mechanical and thermal characteristics. These proceedings reflect the exciting progress made in this field. Successful p-type doping of ZnSe has recently led to the fabrication of blue-green injection lasers in ZnSe; applications of short-wavelength light-emitting devices range from color displays to optical storage. In SiC, advances in growth techniques for bulk as well as epitaxial material have made the commercial production of high-temperature and high-frequency devices possible. For GaN, refinement of growth procedures and new ways of obtaining doped material have resulted in blue-light-emitting diodes and opened the road to the development of laser diodes. Finally, while the quality of artificial diamond is not yet high enough for electronic applications, the promise it holds in terms of unique material properties is encouraging intense activity in the field. This volume contains contributions from recognized experts presently working on different material systems in the field. The papers cover the theoretical, experimental and application-oriented aspects of this exciting topic.
