Abstract
Performance of millimeter-wave (mm-wave) multi-band orthogonal frequency division multiplexing (MB-OFDM) ultrawideband (UWB) signal over fiber transmission system is investigated considering impact of modulation index (MI). Experiments are conducted to verify our theoretical analysis and good agreement is obtained. 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 1800 phase shift between the two MZMs. We demonstrate 30GHz mm-wave wireless that carries three-bands OFDM UWB signals, and error vector magnitude is used to analyze the transmission quality. It is found that the EVM decreases from ~-13.63 to -18.9 dB when increasing the LO modulation index (MI) from 66 to ~117%.
