Abstract
A scheme of photonic orthogonal frequency division multiplexing (OFDM) signal generation and distribution employing copolarized pumps generated by a dual driver Mach-Zehnder modulator and four-wave mixing inside an optical semiconductor amplifier (SOA) is proposed and evaluated by theoretical analysis and simulations. In this proposal, 12 times optical frequency multiplication is utilized to up-convert the intermediate frequency band OFDM signal to the millimeter wave (mm-wave) band. The system performance under various key parameters of the SOA and the input optical signal is evaluated and discussed. The results present useful insight for the practicality of photonic mm-wave signal generation and distribution in the next-generation optical-wireless access network.
