We report on a widely wavelength-tunable fiber-based optical parametric oscillator (FOPO) using four-wave mixing in a photonic crystal fiber and an intracavity spectral filter. By changing the wavelength of a pump laser and the passband of the spectral filter, a tuning range of 90 nm is achieved while keeping the FOPO repetition rate constant.
