Experimental implementations of continuous optical time domain Fourier transformation based on time lenses and optical orthogonal frequency-division multiplexing(OFDM) system are carried out.Such a system is verified through 100-km transmission of 10-Gb/s non-return-to-zero(NRZ) intensity-modulated direct-detection(IM-DD) without any dispersion compensation.The system’s bit error rate(BER) and power penalty are 10~(-12) and 4 dBm,respectively.
