Abstract :
Performance of millimeter-wave (MMW) multiband orthogonal frequency-division-multiplexing (OFDM) ultra-wideband (UWB) signal generation using optical frequency up-conversion and transmission over fiber is experimentally investigated. In this work, we propose an optical frequency quadrupling technique using two cascaded Mach-Zehnder modulators (MZMs) biased at quadrature and driven by the same local oscillator frequency but with 180° phase shift between the two MZMs. We demonstrate 30-GHz MMW wireless that carries three bands of OFDM UWB signals.
