Available in PDF, EPUB and Kindle. Book excerpt: Semiconductor lasers using quantum-dots in their active regions have been reported to exhibit significant performance advantages over their bulk semiconductor and quantum-well counterparts namely: low threshold current, high differential gain and highly temperature stable light-current characteristics. This thesis investigates the lasing characteristics of a ridge-waveguide laser containing seven layers of quantum dots as the active region. A summary of the electrical and optical performance data of the heterostructure quantum dot lasers, as well as previously fabricated quantum well lasers, is presented. The motivation of using InAs quantum dots in the active region is to produce near infrared emission for telecommunication applications.

Download or read book Selected Semiconductor Research written by Ming-Fu Li and published by World Scientific. This book was released on 2011 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book on solid state physics has been written with an emphasis on recent developments in quantum many-body physics approaches. It starts by covering the classical theory of solids and electrons and describes how this classical model has failed. The authors then present the quantum mechanical model of electrons in a lattice and they also discuss the theory of conductivity. Extensive reviews on the topic are provided in a compact manner so that any non-specialist can follow from the beginning.The authors cover the system of magnetism in a similar way and various problems in magnetic materials are discussed. The book also discusses the Ising chain, the Heisenberg model, the Kondo effect and superconductivity, amongst other relevant topics.In the final chapter, the authors present some works related to contemporary research topics, such as quantum entanglement in many-body systems and quantum simulations. They also include a short review of some of the possible applications of solid state quantum information in biological systems.

This book was released on 2013-01-25 with total page 522 pages. Available in PDF, EPUB and Kindle. Book excerpt: This reference book provides a fully integrated novel approach to the development of high-power, single-transverse mode, edge-emitting diode lasers by addressing the complementary topics of device engineering, reliability engineering and device diagnostics in the same book, and thus closes the gap in the current book literature. Diode laser fundamentals are discussed, followed by an elaborate discussion of problem-oriented design guidelines and techniques, and by a systematic treatment of the origins of laser degradation and a thorough exploration of the engineering means to enhance the optical strength of the laser. Stability criteria of critical laser characteristics and key laser robustness factors are discussed along with clear design considerations in the context of reliability engineering approaches and models, and typical programs for reliability tests and laser product qualifications. Novel, advanced diagnostic methods are reviewed to discuss, for the first time in detail in book literature, performance- and reliability-impacting factors such as temperature, stress and material instabilities. Further key features include: practical design guidelines that consider also reliability related effects, key laser robustness factors, basic laser fabrication and packaging issues; detailed discussion of diagnostic investigations of diode lasers, the fundamentals of the applied approaches and techniques, many of them pioneered by the author to be fit-for-purpose and novel in the application; systematic insight into laser degradation modes such as catastrophic optical damage, and a wide range of technologies to increase the optical strength of diode lasers; coverage of basic concepts and techniques of laser reliability engineering with details on a standard commercial high power laser reliability test program. Semiconductor Laser Engineering, Reliability and Diagnostics reflects the extensive expertise of the author in the diode laser field both as a top scientific researcher as well as a key developer of high-power highly reliable devices. With invaluable practical advice, this new reference book is suited to practising researchers in diode laser technologies, and to postgraduate engineering students.
Download or read book Valence Band Structures of a Strained Quantum Well and Applications to Semiconductor Lasers written by Shun-Lien Chuang and published by . This book was released on 1992 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: Strain effects in quantum wells have been intensively investigated for applications to semiconductor lasers, photodetectors and electronic devices such as pseudomorphic high electronic mobility transistors. High quantum efficiency, high power (70 mW CW and 180 mW pulsed operation), modulation-doped In0.8Ga0.2As strained-layer (compression) quantum-well lasers emitting at 1.5 um wavelength have been reported. A record high power output (206 mW CW) strained-layer InGaAs/InP quantum-well laser emitting at 1.48 to 1.51 um using the effects of tension strain has been demonstrated. A very low threshold (92 A/cm2) strained-layer quantum-well laser at 1.6 um has also been obtained.
Download or read book Dependence of LASER Performance on Number of Quantum Wells InAIGaAs Semiconductor LASERS written by and published by . This book was released on 2006 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis is undertaken to understand the trade-off in the performance of semiconductor lasers with increase in well number. Five and seven quantum well InAlGaAs lasers operating at 1300nm were investigated. Seven quantum well lasers showed better optical confinement and characteristic temperature than the five quantum well lasers. Increase in well number lowers threshold current and improves optical confinement factor, characteristic temperature, net gain and material gain with trade off in slope efficiency, differential quantum efficiency and cavity loss. Design curves were plotted to aid laser designers to understand the performance trade off in increasing the well number. Seven quantum well lasers exhibited low threshold current of 13.8mA and high characteristic temperature of 71°c. Five quantum well lasers showed high slope efficiency of 0.198W/A and a low cavity loss of 18/cm. This study also helps in optimizing the number of quantum wells for the given cavity length.
