We report on a mode-locked erbium-doped fiber laser delivering highly-chirped pulses with several tens of nanojoules of energy around 1560 nm and its exploitation to efficiently pump a fiber optical parametric oscillator (FOPO), thus enabling picosec

Tailoring wavelength correlations in fiber-optical sources through nonlinear phenomena could drive many quantum optics applications. However, to date, such correlations have not been explored within fiber-optical parametric oscillators (FOPO), which
