Abstract

In this paper, a novel scheme to generate millimeter-wave with wavelength reuse by using one modulator has been proposed. In such a system, a continuous wave lightwave is intensity-modulated via a dual-arm LiNbO₃ Mach-Zehnder interferometer modulator with DC biased at υ _π and driven by two complementary modulation signals, which are composed of a lower frequency RF cosine signal mixed with baseband signals by an electric mixer and a higher frequency RF cosine signal. The optical carrier is suppressed and the generated optical signal mainly consists of four sidebands, in which only two sidebands carry baseband signals. At the base station, an optical interleaver is used to filter out the proposed optical mm-waves from the sidebands and another IL is used to filter out the wavelength reused for uplink connection from the rest sidebands. The transmission performance of system is analyzed theoretically and numerically.
