A new cost-effective mobile fronthaul architecture has been proposed by designing promising analog radio over fiber (ARoF) transmission system compliant with the next generation ultra-dense wavelength division multiplexing passive optical network (UDWDM-PON). It is conceived for standalone 5G/5G+ mobile communication systems driven by broadband multi-input multi-output (MIMO) millimeter wave data signals using two high spectral efficient modulations. The feasibility of the proposed system was firstly proven in terms of spectral tracing supported by theoretical analysis that disclosed good agreement. Furthermore, the obtained simulation results regarding the system performance evaluation after 22 km bidirectional optical fiber links were revealed high reliable characteristics including error-free transmissions at low receiver sensitivities, and measured power penalties less than 1 dB. In addition, the recovered eye diagrams maintained wide openings with high-quality patterns.

“…Optical heterodyning has been the most widely implemented technique for frequency upconversion in the last years. There are several techniques to implement optical heterodyning aiming to obtain phase-correlated signals with low noise and tunable as reviewed in [71]. The most popular are optical injection locking (OIL), optical phase-lock loop (OPLL), dual-wavelength single-longitudinal mode (SLM) lasers and optoelectronic oscillator (OEO).…”

This paper proposes a mm-wave cellular flexible architecture based on a photonic beamformer network. An overview of integrated optical beamformer technology state-of-the-art is reported considering different implementations, fabrication technologies and the associated design requirements and limitations. A network architecture based on multicore-fiber (MCF) is proposed to operate as fronthaul or backhaul depending on the network configuration and user capacity dynamics. Multi-wavelength operation is achieved employing an optical frequency comb generator capable of providing several phase-correlated optical lines. Following new-radio 5G specifications, both NR 5G frequency ranges (FR) are considered in the proposed network, including FR1 at sub-6 GHz frequency bands, and FR2 in the mm-wave range from 24 to 100 GHz. The work analyses the main subsystems of the integrated photonics beamformer: the laser source which comprises an optical comb, the optical filtering and induced delay subsystems, the arrangement of MCF media to feed different antenna elements and the mm-wave generation subsystem, where optical heterodyning is proposed. The performance of these key subsystems is evaluated experimentally and analyzed by simulation when necessary to assess the proper photonic beamforming network operation.

SummaryOptical millimeter‐wave generation is a predominant approach for the generation of high‐quality carrier signals for future wireless transmissions. This paper proposes an optical frequency 12‐tupling millimeter‐wave generation scheme using three cascaded‐MZMs assisted by polarization multiplexing for carrier suppression. A three‐stage MZM architecture produces the desired sixth‐order sidebands along with the undesired carrier signal. The proper adjustment of polarization direction and angle of polarization rotation lead to the effective suppression of the undesired optical carrier signal. A comprehensive mathematical analysis has been accomplished to evaluate the system's performance, and the obtained results are also validated through simulation findings. The derived results demonstrate that the proposed system is capable of operating over a broad modulation index range extending from 1.5 to 4.5, thereby relaxing the stringent requirements for a constant modulation index. The proposed system generates high‐purity mm‐wave signals with an OSSR of 62.06 dB and an RFSSR of 54.79 dB at a modulation index of 2.6. Moreover, it is also validated that even if the system parameters like modulation index, polarizer rotation angle, and phase difference among RF driving signals deviate from their ideal values to a certain degree, the system performance remains acceptable. The involvement of polarization technique, omission of wavelength‐dependent devices, and a large modulation index operating range make this methodology readily appealing for implementation in radio‐over‐fiber transmissions.
