The demand for data transmission is rising expensively the applications of biomedical sensors data, multimedia technologies, and ultrahigh-definition online video streaming. Such require larger bandwidth with minimum latency seamless service delivery. Radio-over-fiber (RoF), integrated wavelength division multiplexing (WDM) technology, being considered one promising technologies. However, integration optical fiber wireless communication also generates non-linear effects as when number users...

Coping up with the rising bandwidth demands for 5G ultra-high speed applications, utilizing millimeter (MM) wave spectrum data transmission over radio a fiber-based system is ideal approach. In this study, highly conversant and spectrally pure photonic generation of 16-tupled MM signal using series-connected DD-MZM lower modulation index, splitting ratio, wider tunable range presented. A 160-GHz generated through double sideband optical carrier suppression technique having an ratio (OSSR) 69...

Cost and complexity are two important parameters that taken into account while generating transmitting MM waves for 5G network. Generating in optical domain using up-conversion techniques eliminates the requirement of high frequency local oscillator (LO) at central station (CS). This paper reports performance 80 GHz wave signal generated from 5 RF along fiber. However, transmission signals through fiber undergoes dispersion which could be reduced by modulating data on single sideband (SSB)...

A centimeter-scale hybrid plasmonic waveguide (HPW) structure based on a grating is proposed at telecom wavelengths. The high-contrast formed by Si and air placed in an slot created the high-index region for attaining nanoscale optical confinement. High-contrast gratings help enhance propagation length up to 3.6 cm with very low loss of 0.11 dB/mm. Further, extremely large figure merit 1,129,623 (>107) confinement 0.00081/μm2 introduced. In present work, finite-element-method-based COMSOL...
