摘要: Abstract A tunable comb generator (TCG) by cascading a single phase modulator (PM) with two identical intensity modulators (IMs) is proposed for the scalable and reconfigurable generation of flat optical comb. Detailed theoretical analysis performed to find out optimized condition using TCG scalability generated also analyzed under condition. An experiment conducted verify feasibility experimental results agree well prediction. The reconfigurability stability obtained are discussed as in experiment. After that, utilized source wavelength-division multiplexed radio-over-fiber (WDM-RoF) system hybrid WDM orthogonal frequency-division multiple access passive network (WDM-OFDMA-PON). Two corresponding demonstrations presented employing source, respectively. In WDM-RoF system, 17 channels each carrying 16×5 Gb/s non-return-to-zero (NRZ) data have been up-converted 10 GHz simultaneously. WDM-OFDMA-PON, 17-channel OFDM-WDM double-sideband (DSB) signal achieving 10.85 Gb/s traffic per channel successfully transmitted both wired baseband OFDM wireless access.
