title: Photonic millimeter-wave generation from frequency-multiplied Erbium-doped fiber laser pulse-train using purely sinusoidal-wave modulated laser diode.
abstract: Photonic millimeter-wave generation from high-order frequencymultiplied optical pulse-train of Erbium-doped fiber laser (EDFL) harmonic mode-locked at repetition frequency of 1 GHz is demonstrated. A Fabry-Perot laser diode (FPLD) operated at below threshold condition is employed as an intra-cavity optical mode-locker, which is purely sinusoidal-wavemodulated at 1 GHz without any DC biased current in this experiment. The threshold modulating power of 18 dBm for the FPLD is observed for harmonic mode-locking the EDFL. The frequency-multiplication of EDFL pulse-train is implemented by detuning the modulating frequency of the FPLD. At highest repetition rate of 42 GHz, the peak power and pulseswidth of frequency-multiplied EDFL pulse-train are 140 mW and 2.7 ps, respectively.
