Book excerpt: Since the first demonstration of room-temperature operation of self-assembled quantum dot (QD) lasers about a decade ago, there have been great strides in improving the characteristics and performance of these lasers. They currently match or surpass the performance of quantum well lasers. However, there are unique problems that limit the performance of conventional separate confinement heterostructure (SCH) QD lasers compared to what is expected from "ideal" lasers with near singular density of states. In the study reported here, unique insights and solutions to these problems are demonstrated and reliable quantum dot lasers that surpass quantum well lasers in performance characteristics are developed. By utilizing the concepts of tunnel injection and p-doping, 1.0 micrometer and 1.3 micrometer quantum dot lasers with high differential gain, modulation bandwidth ^25GHz, a factor less than unity, and zero chirp have been achieved. This final report summarizes the successful design, fabrication, and characterization of high performance 1.0 micrometer QD-Distributed-Feedback (DFB) lasers, 1.0 micrometer QD-Tunnel-Injection lasers (undoped and p-doped), and 1.3 micrometer p-doped QD lasers. The authors have demonstrated record performance of these unique devices in terms of differential gain, modulation bandwidth, temperature dependence, chirp, and linewidth enhancement factor.

This book was released on 1996 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Strained quantum-well lasers and modulators are studied in this dissertation. Both dc and high-speed performances of these two devices are studied. Theoretical models are developed, and we show very good agreement between the theoretical and experimental results. Strain and quantum size effects on the optical-matrix elements for both TE and TM polarizations of strained quantum wells are studied theoretically, including the spin-orbit coupling. A set of universal curves for the polarization-dependent optical-matrix elements as a function of strain is shown. These curves are very helpful for a quick estimate of the optical-matrix elements for strained quantum-well structures. A complete model with the spin-orbit coupling for strained quantum-well lasers is then presented. Explicit formulas for the momentum-matrix elements are given. The improvement in the threshold current density of tensile strained quantum-well lasers, as compared with that of the unstrained quantum well, is shown to result from the enhanced momentum matrix. The theoretical results show a smaller linewidth enhancement factor for compressively and tensile strained quantum wells than that of the unstrained structure, as has been experimentally observed. Amplified spontaneous emission spectroscopy is used to extract the gain and refractive index spectra systematically. The measured optical gain and refractive index are then compared with our theoretical model for strained quantum-well lasers. We show that a comprehensive theoretical model for calculating the electronic band structure, the optical constants, and the linewidth enhancement factor agrees very well with the experiment. Nonlinear gain coefficients are modeled based on the two-level density matrix formalism. Both spectral-hole burning and carrier beating vibration are included for strained quantum-well structures. Formulas for both self- and cross-polarization nonlinear coefficients are presented. A theoretical model for strained quantum-well modulators including the spin-orbit coupling is then presented. The exciton equation is solved in the momentum space. The symmetrical properties of the exciton Hamiltonian are investigated carefully and shown to reduce the computation time. An interpolation scheme is proposed to properly take into account the continuous exciton states. The strained effects on the performances of modulators are shown and compared with the experimental data.

Available in PDF, EPUB and Kindle. Book excerpt: When this publisher offered me the opportunity to \\Tite a book, some six years ago, I did not hesitate to say yes. I had just spent the last four years of graduate school struggling to understand the physics of strained quantum well lasers, and it seemed to me the whole experience was much more difficult that it should have been. For although many of the results I needed were easy to locate, the underlying physical premises and intervening steps were not. If only I had a book providing the derivations, I could have absorbed them and gone on my way. Such a book lies before you. It provides a unified and self-contained descrip tion of the essential physics of strained quantum well lasers, starting from first principles whenever feasible. The presentation I have chosen requires only the standard introductory background in quantum mechanics, solid state physics, and electromagnetics expected of entering graduate students in physics or elec trical engineering. A single undergraduate course in each of these subjects should be more than sufficient to follow the text. :'Iore advanced material on quantum mechanics is developed and collected in the first chapter. \Vhen pos sible, I have presented the results in a general setting and have later applied them to specific cases of interest. I find this the most satisfying way to ap proach the subject, and it has the additional benefit of solving many problems once and for all.
