Book Description
Energy-efficient Tbit/s optical interconnects are key elements for future communication systems. Three novel optical frequency comb sources are investigated, which have the potential of being integrated in chip-scale Tbit/s transmitters. Such frequency combs provide a large number of carriers. The equidistance of the comb lines helps to minimize spectral guard bands. For each type of comb source, coherent data transmission experiments show the potential for Tbit/s data transmission rates.

Book Description
This book argues that a conscientiously objecting medical professional should receive an exemption only if the grounds of an objector’s refusal are reasonable. It defends a detailed, contextual account of public reasonability suited for healthcare, which builds from the overarching concept of Rawlsian public reason. The author analyzes the main competing positions and maintains that these other views fail precisely due to their systematic inattention to the grounding reasons behind a conscientious objection; he argues that any such view is plausible to the extent that it mimics the ‘reason-giving requirement’ for conscience objections defended in this work. Only reasonable objections can defeat the prior professional obligation to assign primacy to patient well-being, therefore one who refuses a patient’s request for a legally available, medically indicated, and safe service must be able to explain the grounds of their objection in terms understandable to other citizens within the public institutional structure of medicine. The book further offers a novel policy proposal to deploy the Reasonability View: establishing conscientious objector status in medicine. It concludes that the Reasonability View is a viable and attractive position in this debate. A New Theory of Conscientious Objection in Medicine: Justification and Reasonability will be of interest to researchers and advanced students working in bioethics, medical ethics, and philosophy of medicine, as well as thinkers interested in the intersections between law, medical humanities, and philosophy.

Book Description
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.

Book Description
The increasing demand for high capacity, low cost, high compact and energy efficient optical transceivers for data center interconnects requires new technological solutions. In terms of transmitters, optical frequency combs generating a large number of phase coherent optical carriers are attractive solutions for next generation datacenter interconnects, and along with wavelength division multiplexing and advanced modulation formats can demonstrate unprecedented transmission capacities. In the framework of European project BIG PIPES (Broadband Integrated and Green Photonic Interconnects for High-Performance Computing and Enterprise Systems), this thesis investigates the generation of optical frequency combs using single-section mode-locked lasers based on InAs/InP Quantum-Dash and InGaAsP/InP Quantum-Well semiconductor nanostructures. These novel light sources, based on new active layer structures and cavity designs are extensively analyzed to meet the requirements of the project. Comprehensive investigation of amplitude and phase noise of these optical frequency comb sources is performed with advanced measurement techniques, to evaluate the feasibility of their use in high data rate transmission systems. Record Multi-Terabit per second per chip capacities and reasonably low energy per bit consumption are readily demonstrated, making them well suited for next generation datacenter interconnects.

Book Description
Optical communication systems carry the bulk of all data traffic worldwide. This book introduces multi-Terabit/s transmission systems and three key technologies for next generation networks. A software-defined multi-format transmitter, an optical comb source and an optical processing scheme for the fast Fourier transform for Tbit/s signals. Three world records demonstrate the potential: The first single laser 10 Tbit/s and 26 Tbit/s OFDM and the first 32.5 Tbit/s Nyquist WDM experiments.

Book Description
This book, now in its fourth edition, is a well-known classic on the ultrafast nonlinear and linear processes responsible for supercontinuum generation. The book begins with chapters reviewing the experimental and theoretical understanding of the field along with key applications developed since the discovery of the supercontinuum effect. The chapters that follow cover recent research activity on supercontinuum phenomena, novel applications, and advances achieved since the publication of the previous edition. The new chapters focus on: filamentation in gases, air, and condensed media; conical emission by four-wave mixing and X-waves; electronic self-phase mechanism; higher harmonics generation; attosecond laser pulses; complex vector beam supercontinuum; higher order self-phase modulation and cross-phase modulation; nonlinear supercontinuum interference in uniaxial crystals; new nonlinear microscopes involving supercontinuum and ultrafast lasers with biomedical applications; and other current supercontinuum applications in communications. The Supercontinuum Laser Source is a definitive work by one of the discoverers of the white light effect. It is indispensable reading for any researcher or student working in the field of ultrafast laser physics.

Book Description
In this book, silicon photonic integrated circuits are combined with electro-optic organic materials for realizing energy-efficient modulators with unprecedented performance. These silicon-organic hybrid Mach-Zehnder modulators feature a compact size, sub-Volt drive voltages, and they support data rates up to 84 Gbit/s. In addition, a wet chemical waveguide fabrication scheme and an efficient fiber-chip coupling scheme are presented.

Book Description
Among the various elements of the silicon photonics platform, electro-optic IQ modulators play an important role. In this book, silicon-organic hybrid (SOH) integration is used to realize electro-optic IQ modulators for complex signal processing. Leveraging the high nonlinearity of organic materials, SOH IQ modulators provide low energy consumption for high-speed data transmission and frequency shifting. Furthermore, the device design is adapted for commercial foundry processes.
