Simulation studies on the generation of 110 GHz mm-wave for 5G applications

Stable and noise free generation of mm-wave demands the utilization of optical technology for the 5G communication networks. Radio-over-Fiber technology (RoF) is a favourable technology for the generation of mm-wave. In this paper, a simulation setup of the full duplex mm-wave RoF system comprising Fiber Bragg Grating (FBG) has been developed and comparative analysis of noise and output signal power levels of different modulators has also been performed. Finally, generation of 110 GHz mm-wave using ElectroAbsorption Modulator (EAM) has been presented. The proposed system has the advantage of reusing the same wavelength in both uplink and downlink.
