Fiber optical parametric oscillator pumped by a wavelength tunable bursted GHz frequency comb

We present a gigahertz (GHz) repetition rate fiber opticalparametric oscillator (FOPO) pumped by a wavelength-tunable electro-optic (EO) frequency comb operatingnear 1030 nm. This FOPO is based on a 24 cm long pho-tonic crystal fiber and operates in burst mode, drivenby picosecond pulses with a repetition rate of 16 GHz.It generates picosecond signal and idler pulses tunablefrom 866 nm to 901 nm and 1225 nm to 1300 nm, respec-tively. The maximum overall conversion efficiency frompump to signal and idler reaches 41%. We also report thebuild-up and relaxation dynamics of the signal pulse.The experimental measurements of the FOPO tuning,and parametric fluorescence spectra show good agree-ment with our numerical simulations.
