Abstract:

A novel method on transmission of OFDM signal based on broadband optical source is proposed. A result of 1.0 GHz bandwidth OFDM signal with 16QAM-512 subcarrier and 2.0 Gbit/s centered at 3.0 GHz was accomplished experimentally. The EVM characterization and bias point of the system are also discussed.

Key words: OFDM, broadband optical source, vector signal, microwave photonics
