Laser Pointer Diode

This book covers the device physics of semiconductor lasers in five chapters written by recognized experts in this field. The volume begins by introducing the basic mechanisms of optical gain in semiconductors and the role of quantum confinement in modern quantum well diode lasers. Subsequent chapters treat the effects of built-in strain, one of the important recent advances in the technology of these lasers, and the physical mechanisms underlying the dynamics and high speed modulation of these devices. The book concludes with chapters addressing the control of photon states in squeezed-light and microcavity structures, and electron states in low dimensional quantum wire and quantum dot lasers. The book offers useful information for both readers unfamiliar with semiconductor lasers, through the introductory parts of each chapter, as well as a state-of-the-art discussion of some of the most advanced semiconductor laser structures, intended for readers engaged in research in this field. This book may also serve as an introduction for the companion volume, Semiconductor Lasers II: Materials and Structures, which presents further details on the different material systems and laser structures used for achieving specific diode laser performance features.

Diode Lasers and Photonic Integrated Circuits provides a fresh look at this fast-growing technology. Written specifically as an engineering text, it initially builds upon practical and elementary aspects as a preparation for more complex physical problems treated in later chapters. To treat complex cavity designs, the transmission matrix approach is emphasized because it is especially relevant to the widespread use of computers, as well as the rise of vertical-cavity lasers. Throughout, the material is supplemented with extensive appendices, addressing readers of varied backgrounds, and providing both review material and details of advanced topics. What emerges is a comprehensive, self-contained treatment of diode lasers and photonic integrated circuits that makes this an ideal textbook for a one-year course at either the senior or graduate level. This book is also an excellent professional reference for experienced engineers and researchers in microwave and optoelectronics technology.

Laser diode - A laser diode is a laser where the active medium is a semiconductor similar to that found in a light-emitting diode. The most common and practical type of laser diode is formed from a p-n junction and powered by injected electrical current.

Laser diode rate equations - The laser diode rate equations model the electrical and optical performance of a laser diode. This system of ordinary differential equations relates the number or density of photons and charge carriers (electrons) in the device to the injection current and to device and material parameters such as carrier lifetime, photon lifetime, and the optical gain.

Laser pointer - A laser pointer is a product that includes a small, inexpensive laser in a portable, pen-shaped format. Due to their low output, laser pointers do not project a visible beam in normal, clear air - rather, their light is visible as a small point of light where the beam intersects a surface.

Diode pumped solid state laser - Diode pumped solid state (DPSS) lasers are solid-state lasers made by pumping a solid gain medium, for example, a ruby or a neodymium-doped YAG crystal, with a laser diode.
