“…In an RoF system, the cost-effective and high quality generation of high frequency mm-wave signals is a key technology that requires further development toward high-frequency bands, especially for frequencies above 40 GHz [12][13][14]. Compared with the conventional electrical method, the optical method is preferable [15][16][17]. By beating the two high-order optical sidebands with good coherence in a square-law photodetector (PD), a laser with an optical external phase or intensity modulator is a promising and attractive technology for the generation of high-frequency mm-wave signals, the frequency of which can be several-folds that of the radio frequency (RF) local oscillator [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33].…”

Abstract-In this paper, we propose a new approach to generate quadrupling-frequency optical millimeter-wave (mm-wave) signal with carrier suppression by using two parallel Mach-Zehnder modulators (MZMs) in Radio-over-fiber (RoF) system. Among the numerous properties of this approach, the most important is that a filterless optical mm-wave at 60 GHz with an optical sideband suppression ratio (OSSR) as high as 40 dB can be obtained when the extinction ratio of the MZM is 25 dB. Simplicity and cost-effectiveness have made this approach a compelling candidate for future wave-division-multiplexing RoF systems.Theoretical analysis is conducted to suppress the undesired optical sidebands for the high-quality generation of frequency quadrupling mm-wave signal. The simulation results show that a 60 GHz mm-wave is generated from a 15 GHz radio frequency (RF) oscillator with an OSSR as high as 40 dB and an radio frequency spurious suppression ratio (RFSSR) exceeding 35 dB without any optical or electrical filter when the extinction ratio of the MZM is 25 dB. Furthermore, the effect of the non-ideal RF-driven voltage as well as the phase difference of RF-driven signals applied to the two MZMs on OSSR and RFSSR is discussed and analyzed. Finally, we establish a RoF system through simulation to verify the transmission performance of the proposed scheme. The Q-factor performance and eye patterns are given.

Abstract-Advanced cost reduction and performance improvement techniques conceived for Radio Over Fiber (ROF) communications are considered. ROF techniques are expected to form the backbone of the future 5G generation of wireless networks. The achievable link performance and the associated deployement cost constitute the most salient metrics of a ROF architecture. In this paper, we commence by providing a rudimentary overview of the ROF architecture and then elaborate on ROF techniques designed for improving the attainable system performance. We conclude by describing the ROF techniques conceived for reducing the ROF system installation costs.

“…A la fecha se han realizado diferentes trabajos que demuestran las ventajas de implementar sistemas de transporte de señales de radiofrecuencia sobre enlaces de fibra óptica en diferentes escenarios y aplicaciones. En [3] se discuten las tecnologías habilitantes que permiten el desarrollo de sistemas RoF que incluye esquemas para generación óptica de ondas milimétricas y elevadores de frecuencia, en [4] se presentan varias técnicas para la implementación de redes de acceso ópticas-inalámbricas basadas en procesos de modulación externa realizada en un modulador tipo Mach-Zehnder (MZ). Por otro lado, la modulación simultánea de señales en banda base y RF en un modulador óptico se demostró experimentalmente en [5].…”
