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.
