Ultra-Broadband InAs/InP Quantum-Dash Laser in Optical Communications: Device and System Level Investigation by Emad Alkhazraji Pdf

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.

Quantum Dash Laser in WDM L-band Communication Systems by Emad Alkhazraji Pdf

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.

The book addresses issues associated with physics and technology of injection lasers based on self-organized quantum dots. Fundamental and technological aspects of quantum dot edge-emitting lasers and VCSELs, their current status and future prospects are summarized and reviewed. Basic principles of QD formation using self-organization phenomena are reviewed. Structural and optical properties of self-organized QDs are considered with a number of examples in different material systems. Recent achievements in controlling the QD properties including the effects of vertical stacking, changing the matrix bandgap and the surface density of QDs are reviewed. The authors focus on the use of self-organized quantum dots in laser structures, fabrication and characterization of edge and surface emitting diode lasers, their properties and optimization with special attention paid to the relationship between structural and electronic properties of QDs and laser characteristics.

Millimeter-Wave Radio-over-Fiber Links based on Mode-Locked Laser Diodes by Brendel, Friederike Pdf

Radio communications in the range of 60 GHz enable multi-Gigabit/s network access in indoor environments. Due to the propagation characteristics of such signals only very short range radio transmission is feasible. In order to distribute these signals across large distances, analog transmission over optical fiber is considered. In this work, mode-locked laser diodes serve as optoelectronic oscillators for the generation of such signals. Their system-relevant properties are studied in detail.
