PHOTONIC GENERATION OF MICROWAVE CARRIER EMPLOYING OFM IN RADIO OVER FIBER

Abstract

A novel, simplest and cost-effective approach, Optical Frequency Multiplication (OFM) is proposed and experimentally demonstrated for the generation of microwave radio frequencies (RFs) optically and deliver them from a central station to remote radio access units. Simulation results show that the frequency and intensity of the generated higher-order harmonic components basically depend on frequency deviation, FSR, Sweep frequency and laser filter misalignment. The non-integer value of N (ratio of optical peak frequency deviation to the filter FSR) generated the unwanted harmonics component. It is also verified that 4th, 6th and 8th harmonics have the highest signal strength at 12 GHz FSR with a frequency deviation of 24 GHz.
