Hybrid Opto/Wireless Systems for Multi-Gigabit Networks at Millimeter Frequencies

This doctoral thesis presents comprehensive research on hybrid optical-wireless systems designed for multi-gigabit communications at 60 GHz millimeter-wave frequencies. The work covers mode-locked lasers (MLL) with quantum dot technology, optical fiber propagation effects, and radio-over-fiber architectures for high-speed wireless networks. The thesis includes detailed characterization of Q-dash semiconductor lasers, analysis of chromatic dispersion impacts on RF power transmission, and investigation of optically injected mode-locked lasers. Technical topics encompass intensity modulation techniques, asymmetric Mach-Zehnder interferometer implementations, and system architectures compliant with IEEE 802.15.3c and ECMA 387 standards. Experimental validation demonstrates practical implementation of 60 GHz communication systems using optical generation methods. This research addresses the fundamental challenges of combining optical fiber transmission with millimeter-wave wireless distribution for next-generation broadband communication networks.
