Hybrid Opto/Wireless Systems for Multi-Gigabit Networks at Millimeter Frequencies
This doctoral thesis presents comprehensive research on hybrid optical-wireless systems engineered for multi-gigabit communications at 60 GHz millimeter-wave frequencies. The work explores mode-locked lasers incorporating quantum dot technology, optical fiber propagation characteristics, and radio-over-fiber architectures optimized for high-speed wireless networks. Key technical content includes detailed characterization of quantum-dash semiconductor lasers, systematic analysis of chromatic dispersion effects on RF power transmission, and investigation of optically injected mode-locked laser performance. The thesis addresses intensity modulation techniques, asymmetric Mach-Zehnder interferometer designs, and complete system architectures meeting IEEE 802.15.3c and ECMA 387 standards for millimeter-wave communications. Experimental work demonstrates practical 60 GHz system implementation using optical signal generation methods, tackling the fundamental engineering challenges of merging fiber-optic backbone transmission with millimeter-wave wireless distribution for next-generation broadband networks.
Photonic Frequency Converter Performance Enhancement for Satellite Payloads
Doctoral thesis presenting a comprehensive study of RF frequency conversion modules engineered for satellite telecommunications payloads using integrated photonic components. This work directly addresses the practical challenge of supporting expanding satellite bandwidth demand while reducing payload weight and system complexity. The research examines satellite communication network topologies, payload architectural frameworks, RF mixer design fundamentals, and the integration of photonic technologies into operational systems. The thesis develops and rigorously evaluates two distinct converter architectures: one leveraging electro-absorption modulators and another employing semiconductor optical amplifiers. Detailed simulation analysis conducted with VPIphotonics software documents conversion gain performance, noise figure characteristics, signal isolation metrics, and third-order interception point behavior across the tested frequency ranges. Three laboratory-validated converter designs demonstrate that compact, fully integrated photonic frequency converters can meet the stringent performance requirements of next-generation satellite systems while delivering substantial reductions in mass and physical volume compared to conventional RF-based conversion approaches.
