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.

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.

To keep up with the ever-increasing data transmission speed needs, data center interconnects are scaling up to provide multi-Tbit/s connectivity. These links require a high number of WDM channels, while the associated transceivers should be compact and energy efficient. Scaling the number of channels, however, is still limited by the lack of adequate optical sources. In this book, we investigate novel chip-scale frequency comb generators as multi-wavelength light sources for Tbit/s WDM links.

Silicon-organic hybrid (SOH) modulators add a highly efficient nonlinear organic electro-optic cladding material to the silicon photonic platform, thereby enabling efficient electro-optic modulation. In this book, the application potential of SOH modulators is investigated. Proof-of-principle experiments show that they can be used for high-speed communications at symbol rates up to 100 GBd and operated directly from a field-programmable gate array (FPGA) without additional driver amplifiers.

Since its invention in 1962, the semiconductor laser has come a long way. Advances in material purity and epitaxial growth techniques have led to a variety of semiconductor lasers covering a wide wavelength range of 0. 3- 100 ~m. The development during the 1970s of GaAs semiconductor lasers, emitting in the near-infrared region of 0. 8-0. 9 ~m, resulted in their use for the first generation of optical fiber communication systems. However, to take advantage oflow losses in silica fibers occurring around 1. 3 and 1. 55 ~m, the emphasis soon shifted toward long-wavelength semiconductor lasers. The material system of choice in this wavelength range has been the quaternary alloy InGaAsP. During the last five years or so, the intense development effort devoted to InGaAsP lasers has resulted in a technology mature enough that lightwave transmission systems using InGaAsP lasers are currently being deployed throughout the world. This book is intended to provide a comprehensive account of long-wave length semiconductor lasers. Particular attention is paid to InGaAsP lasers, although we also consider semiconductor lasers operating at longer wave lengths. The objective is to provide an up-to-date understanding of semicon ductor lasers while incorporating recent research results that are not yet available in the book form. Although InGaAsP lasers are often used as an example, the basic concepts discussed in this text apply to all semiconductor lasers, irrespective of their wavelengths.
