Abstract

We present a gigahertz (GHz) repetition rate fiber optical parametric oscillator (FOPO) pumped in burst mode by a wavelength-tunable electro-optic (EO) frequency comb operating near 1030 nm. This FOPO is based on a 24 cm long photonic crystal fiber and driven by picosecond pulses at a repetition rate of 16 GHz. It generates bursts of picosecond signal and idler pulses tunable from 866 nm to 901 nm and 1225 nm to 1300 nm, respectively. We achieved an overall conversion efficiency of 41% from pump to signal and idler. We also report the build-up and relaxation dynamics of the signal pulse bursts. The experimental measurements of the FOPO tuning and parametric fluorescence spectra show good agreement with our numerical simulations.
