This book was released on 2017-02-10 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantum dash based laser diodes have attracted the focus of study and research in the very recent years due to what they possess of myriad advantages that make them ideal for several applications. Atop said advantages is their peculiar ultra-broadband emission as a result of the inherent inhomogeneous nature of the growth process of quantum dashes. This book investigates a novel multi-stacked chirped InAs/InP quantum dash-in-well laser that introduces an extra layer of inhomogeneity. The investigation of this laser is carried out at two levels: device level and system level. In device level, the fundamental laser diode characterization experiments are performed to extract its principle parameters. Thereafter, the investigation scope is shifted towards pulsed operation modes of higher-ordered duty-cycles and continuous wave operations. The device-level characterization is concluded by investigating the temperature dependent lasing spectral profiles at different geometrical configurations, current injections, and temperatures. Finally, the obtained results are used to optimize different operation parameters that achieved a successful implementation in optical communication systems.

Available in PDF, EPUB and Kindle. Book excerpt: Wavelength division multiplexed passive optical networks are perceived as the ultimate form of next-generation passive optical network that show promising outlooks in meeting the ever-growing demand of telecommunication capacities and internet traffic. In this book, an InAs/InP quantum dash laser is investigated as an ideal contender to meeting this demand owing to is broadband emission, which allows for expanding the utilizable bandwidth away from the over-exhausted C-band and to accommodating more subscribers for less capital expenditure. Firstly, the device is inspected as a tunable light source with a total emission-wavelength tuning range of 30 nm due to its inhomogeneous active region. Thereafter, the device is investigated in two-sectioned configurations to realize other monolithic devices. Lastly, the quantum dash active region is examined in terms of its electro-absorption (EA) and electro-optic (EO) characteristics. On another front, the quantum dash laser is employed to achieve the first demonstration of WDM transmission in the L-band over a single transmitter with an aggregate data rate of 384 Gbit/s with three simultaneous channels in DP-QPSK modulation scheme.

Book excerpt: This thesis deals with the dynamics of state-of-the-art nanophotonic semiconductor structures, providing essential information on fundamental aspects of nonlinear dynamical systems on the one hand, and technological applications in modern telecommunication on the other. Three different complex laser structures are considered in detail: (i) a quantum-dot-based semiconductor laser under optical injection from a master laser, (ii) a quantum-dot laser with optical feedback from an external resonator, and (iii) a passively mode-locked quantum-well semiconductor laser with saturable absorber under optical feedback from an external resonator. Using a broad spectrum of methods, both numerical and analytical, this work achieves new fundamental insights into the interplay of microscopically based nonlinear laser dynamics and optical perturbations by delayed feedback and injection.

Book excerpt: This book presents the first comprehensive overview of the properties and fabrication methods of GaN-based power transistors, with contributions from the most active research groups in the field. It describes how gallium nitride has emerged as an excellent material for the fabrication of power transistors; thanks to the high energy gap, high breakdown field, and saturation velocity of GaN, these devices can reach breakdown voltages beyond the kV range, and very high switching frequencies, thus being suitable for application in power conversion systems. Based on GaN, switching-mode power converters with efficiency in excess of 99 % have been already demonstrated, thus clearing the way for massive adoption of GaN transistors in the power conversion market. This is expected to have important advantages at both the environmental and economic level, since power conversion losses account for 10 % of global electricity consumption. The first part of the book describes the properties and advantages of gallium nitride compared to conventional semiconductor materials. The second part of the book describes the techniques used for device fabrication, and the methods for GaN-on-Silicon mass production. Specific attention is paid to the three most advanced device structures: lateral transistors, vertical power devices, and nanowire-based HEMTs. Other relevant topics covered by the book are the strategies for normally-off operation, and the problems related to device reliability. The last chapter reviews the switching characteristics of GaN HEMTs based on a systems level approach. This book is a unique reference for people working in the materials, device and power electronics fields; it provides interdisciplinary information on material growth, device fabrication, reliability issues and circuit-level switching investigation.
