主　　题：Millimeter waves Phase modulation 

摘      要：A scheme for the photonic generation of frequency-tunable millimeter wave and terahertz wave signals based on a highly flat optical frequency comb is proposed and demonstrated *** frequency comb is generated using two cascaded phase modulators（PMs）and an electro-absorption modulator（EAM）.The frequency comb covers a 440-GHz frequency range,with 40-GHz comb spacing and less than 2-dB amplitude *** filtering out two of the comb lines with 50 dB out of the band suppression ratio,high frequency-purity and low phase noise millimeter wave or terahertz wave signals are successfully generated,with frequencies ranging from 40 to 440 GHz.
