Abstract

Cellular networks that use the millimeter-Wave (mm-W) spectrum holds a great promise to revolutionize wireless industry. Nevertheless, the generation and transportation of mm-W signals in the electrical-domain are unfeasible owing to the high air link loss and electromagnetic interference. Generating mm-W signals in the optical-domain, i.e., over an optical fiber will allow sending wireless signals for a long distance. This study presents an evaluation of the Optical Frequency Upconversion (OFU) techniques based on advanced Mach-Zehnder Modulator (MZM) for optical generation and transportation of mm-W wireless signals. Four types of OFU techniques will be compared: frequency-doubling, frequency-quadrupling, frequency-sixtupling and frequency-octupling. We begin by reviewing selected OFU techniques that enable to double, quadruple, sixtuple or octuple an Radio Frequency (RF) and highlighting drawbacks and benefits. Then, a comparison in terms of modulation index, bias drifting and modulation efficiency is presented to show the trade-off between OFU techniques complexity and cost. Comparison of OFU techniques and results from simulation analysis reveal that the frequency quadrupling technique is a robust and more desirable choice for optical generation and transportation of mm-W wireless signals.
