Novel THz device concepts and signal processing schemes are introduced and experimentally confirmed. Record-high data rates are achieved with a simple envelope detector at the receiver. Moreover, a THz communication system using an optoelectronic receiver and a photonic local oscillator is shown for the first time, and a new class of devices for THz transmitters and receivers is investigated which enables a monolithic co-integration of THz components with advanced silicon photonic circuits.
Moral Development and Reality explores the nature of moral development, human behavior, and social interconnections. The exploration elucidates the full range of moral development, from superficial perception to a deeper understanding and feeling through social perspective-taking. By comparing, contrasting, and going beyond the key theories of preeminent thinkers Lawrence Kohlberg, Martin Hoffman, and Jonathan Haidt, author John C. Gibbs tackles vital questions: What exactly is morality and its development? Can the key theoretical perspectives be integrated? What accounts for prosocial behavior, and how can we understand and treat antisocial behavior? Does moral development, including moment...
Diffractive lens arrays are proposed in this work for application in reflected-light confocal microscopes. They have overcome the limitations between fields of view and resolution of traditional objectives. Experiments of multi-spot confocal imaging in surface metrology and fluorescence microscopy have been demonstrated based on the proposed concepts, which have shown capabilities of high-resolution measurement over a large area.

This work describes the OFDM-based MIMO Radar-Communication System, intended for operation in a multiple-user network, especially the automotive sector in the vehicle-to vehicle/infrastructure network. The OFDM signals however are weak towards frequency offsets causing subcarrier misalignment and corrupts the radar estimation and the demodulation of the communication signal. A simple yet effective interference cancellation algorithm is detailed here with real time measurement verification.
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.

High-speed electro-optic modulators in silicon platform are introduced and experimentally verified. The devices rely on plasmonic and photonic slot waveguides and are combined with efficient organic electro-optic materials. The bandwidth limitation of conventional silicon-organic-hybrid modulators is circumvented by capacitive coupling of the microwave signal. An advanced terahertz link that upconverts data directly from a 360 GHz carrier to an optical carrier is demonstrated for the first time.
