A cost-effective ROF system employing FBG and DML to generate optical mm-wave

Abstract

We have investigated and experimentally demonstrated a ROF system employing FBG and low-cost DML to generate optical mm-wave. We employ FBG because the bandwidth of the optical modulator is largely reduced and the architecture of the ROF system is simpler. Because no expensive broadband external modulator is used, the overall system is considered as a cost-effective solution. This novel scheme employs low-cost DML to generate mm-wave signal which is a practical scheme to be applied for future broadband access networks. Full Text: PDF References L. Xu and T.
