Fifth−generation (5G) and millimeter−waves (MM−W) hold tremendous promise to provide opportunities torevolutionize education, healthcare, business, and agriculture.Nevertheless, the generation of MM−W in the electrical−domain is infeasible due to the bandwidth limitation of electronic componentsand radio frequency (RF) interference. The capability to generate MM−W in the optical−domain can provide transportation ofMM−W with low loss from switching center to remote base stations. The present paper is focusing on electro−opticalup−conversion (EOU) techniques for optical generation and transmission of 60−GHz MM−W signal. A comparative study iscarried out between three different EOU techniques: frequency−quadrupling, frequency sextupling and frequency−octotupling. The comparative study aims at showing the strengths and weaknesses of three EOU techniques and evaluatingeach technique in terms of electrical spurious suppression ratio (ESSR), as well as in terms of the influence of non−ideal phaseshifting. The performance of the three EOU techniques after transmission over optical fiber is evaluated by eye pattern test. Theresults of the simulation confirm that the frequency−quadrupling outperforms frequency− sextupling and frequency− octotuplingtechniques.
