Fiber optical parametric amplified optical direct-detection OFDM signal with intensity modulation transfer blocking.
A fiber optical parametric amplified optical orthogonal frequency division multiplexing (OFDM) signal with intensity modulation transfer (IMT) blocking is proposed. A novel blank carrier blocking method is adopted to suppress pump to signal intensity interference. Compared with regular optical signal, the IMT induced interference can be well blocked in the experiment. The error vector magnitude (EVM) and signal gain are also investigated in the experiment.
