“…Aasif et al generated a frequency 16 tupled signal through cascaded connection of two parallel MZM and found that OSSR along with RFSSR are independent of extinction ratio of MZM (14) . Dongfei Wang et al generated 160 GHz Mm wave signal using optical attenuator and two MZM biasing at maximum transmission point (MTP) and obtained OSSR of 31.35 dB and RFSSR of 24.11 dB (15) .…”

Objectives: To find out how fiber distribution system could be utilized for 5G based futuristic higher capacity and lower latency front haul transmission system. Findings: Integrating the transmission of Millimeter wave (Mm wave) signals over the Radio over Fiber (RoF) system i.e. Mm-RoF can be seen as a promising candidate that would satisfy the requirement imposed by 5G wireless system. Further, optical generation of Mm wave signals is a major concern that needs to be taken care of and some appropriate hybrid photonic generation methods should be employed for Mm wave signal distribution over the RoF system that incur lower installation cost and higher transmission performance. Applications: This will enrich the researchers with valuable content on single platform and motivate them to undertake the research work towards the advancement in the photonic generation of Mm wave signals over the RoF network for 5G applications with reduced system cost and complexity.

“…802.15.3d -2017, primarily illustrates the feasibility of Sub-THz communications [1,2]. Compared with the conventional technology in electrical domain, the optical generation scheme for millimeter wave (mm-wave) is desirable, since it can produce signal with higher frequency, wider bandwidth, and anti-electromagnetic interference [3]. Therefore, the optical generation of high frequency mm-wave or Sub-Terahertz wave has aroused much interest in recent years.…”

A novel scheme based on polarization modulators to generate Sub-Terahertz wave (Sub-THz) signal with frequency 32-tupling is proposed. The system consists of two subsystems in cascade, and each subsystem consists of 4 paralleled polarization modulators. In this scheme, by properly controlling two subsystems, an optical signal with optical carrier and ±16th-order optical sidebands is achieved. Next, by adjusting the optical attenuator and optical phase shifter, the optical carrier can be canceled. Finally, the Sub-THz wave with frequency 32-tupling can be obtained after beaten in the photodetector. The results show the ±16th-order optical sideband suppression ratio (OSSR) is derived as 55.7 dB and the radio frequency sideband suppression ratio (RFSSR) of the 32-tupling Sub-THz wave is derived as 43.66 dB, which are consistent with the theoretical analysis very well. Meanwhile, the effects of phase offset, modulation index, and attenuator deviation on suppression ratio are analyzed.

“…Recently, several generation techniques have been reported with a 16 FMF utilizing a two-cascaded dual parallel MZM configuration [6][7][8], parallel combination of two cascaded MZM [9], cascaded parallel MZM [10,11], and a feedforward modulation [12]. Dongfei wang [13] proposed a generation method with a two-cascaded MZM but with a higher modulation index (>>7) requiring a high voltage radio frequency signal which in turn increases the system sensitivity. These schemes employ a filter for generating desired harmonics which not only increases system complexity but also reduces its tunability range and conversion efficiency.…”

Coping up with the rising bandwidth demands for 5G ultra-high speed applications, utilizing millimeter (MM) wave spectrum for data transmission over the radio over a fiber-based system is the ideal approach. In this study, a highly conversant and spectrally pure photonic generation of a 16-tupled MM wave signal using a series-connected DD-MZM with a lower modulation index, a splitting ratio, and a wider tunable range is presented. A 160-GHz MM wave is generated through a double sideband optical carrier suppression technique having an optical sideband suppression ratio (OSSR) of 69 dB and a radio frequency sideband suppression ratio (RSSR) of 40 dB. However, the OSSR and the RSSR are tunable with values greater than 15 dB when the modulation index (M.I.) varies from 2.778 to 2.873, ±8° phase drift, and a 15-dB enhancement in the OSSR with a wider nonideal parameter variation range giving acceptable performance can be seen in the model as compared with previous research works.
