This book focuses on a novel phenomenon named photon breeding. It is applied to realizing light-emitting diodes and lasers made of indirect-transition-type silicon bulk crystals in which the light-emission principle is based on dressed photons. After presenting physical pictures of dressed photons and dressed-photon phonons, the principle of light emission by using dressed-photon phonons is reviewed. A novel phenomenon named photon breeding is also reviewed. Next, the fabrication and operation of light emitting diodes and lasers are described The role of coherent phonons in these devices is discussed. Finally, light-emitting diodes using other relevant crystals are described and other relevant devices are also reviewed.

A fascinating insight into the state-of-the-art in silicon microphotonics and on what we can expect in the near future. The book presents an overview of the current understanding of getting light from silicon. It concentrates mainly on low dimensional silicon structures, like quantum dots, wires and wells, but covers also alternative approaches like porous silicon and the doping of silicon with rare-earths. The emphasis is on the experimental and theoretical achievements concerning the optoelectronic properties of confined silicon structures obtained during recent years. Silicon based photonic crystals are in particular considered. An in depth discussion of the route towards a silicon laser is presented.

Silicon, the leading material in microelectronics during the last four decades, also promises to be the key material in the future. Despite many claims that silicon technology has reached fundamental limits, the performance of silicon microelectronics continues to improve steadily. The same holds for almost all the applications for which Si was considered to be unsuitable. The main exception to this positive trend is the silicon laser, which has not been demonstrated to date. The main reason for this comes from a fundamental limitation related to the indirect nature of the Si band-gap. In the recent past, many different approaches have been taken to achieve this goal: dislocated silicon, extremely pure silicon, silicon nanocrystals, porous silicon, Er doped Si-Ge, SiGe alloys and multiquantum wells, SiGe quantum dots, SiGe quantum cascade structures, shallow impurity centers in silicon and Er doped silicon. All of these are abundantly illustrated in the present book.

Luminescence and the Light Emitting Diode: The Basics and Technology of LEDS and the Luminescence Properties of the Materials focuses on the basic physics and technology of light emitting diodes (LEDS) and pn junction lasers as well as their luminescence properties. Optical processes in semiconductors and the useful devices which can be made are discussed. Comprised of 10 chapters, this book begins with an introduction to the crystal structure and growth, as well as the optical and electrical properties of LED materials. The detailed fabrication of the LED is then considered, along with the luminescence of the material and the diode light emission. Subsequent chapters explore solid-state lasers made from LED materials; the equipment used to measure luminescence, cathodoluminescence, and diode electro-optic characteristics; and luminescence in gallium arsenide, GaAs1-xPx, and gallium phosphide. Other LED materials such as silicon carbide and ternary semiconducting compounds are also surveyed. The text concludes with a brief chapter that describes some of the applications of LEDs and LED products. This monograph will be of value to students and non-graduate engineers with an interest in LEDs.

The "blue laser" is an exciting new device used in physics. The potential is now being recognized for its development into a commercial lighting system using about a tenth of the power and with a thousand times the operating lifetime of a comparable conventional system. This comprehensive work introduces the subject at a level suitable for graduate students. It covers the basics physics of light emitting diodes (LEDs) and laser diodes (LDs) based on gallium nitride and related nitride semiconductors, and gives an outline of their structural, transport and optical properties, and the relevant device physics. It begins with the fundamentals, and covers both theory and experiment, as well as an examination of actual and potential device applications. Shuji Nakamura and Nichia Chemicals Industries made the initial breakthroughs in the field, and these have revealed that LEDs and LDs are a sophisticated physical phenomenon and a commercial reality.
