The emerging wireless communication networks provides many opportunities for photonics technologies to play in the realization of the next generation integrated optical/wireless networks. Millimeter wave Radio over fiber (MMw-ROF) systems has the advantages of a fiber optic link and a free space radio path. The optical network technology, which is considered as the backbone of virtually all communication networks, has evolved concurrently to the wireless networks to achieve the demands of the future generation. The emerging technology such as Radio-Over-Fiber (ROF) is one of the latest advancements in the area of optical networks and has a tremendous potential. The introduction of ROF into mobile front hauling networks divides the front haul to wireless and wired networks. ROF technology is capable of directly converting an optical signal to extremely frequency signal range by utilizing a photonic direct up-conversion scheme. Millimeter wave technology integrated with a ROF system is one of the promising technologies that could deliver high-speed radio transmission with seamless convergence between optical and radio signals. The photonic generation of the MMwave signal from ROF link is essentially considered to be a vital process that helps to keep the remote cells simple, cost-effective as well as energy efficient. This technology also guarantees a low-latency transmission for the wireless MM wave signals, thus could provide a satisfactory solution with excellent flexibility for a mobile broadband access network. Therefore, the integration of fiber and MM wave links could have a huge potential in optical network technology owing to its.
