We present a complete set of measurements and numerical simulations of a femtosecond soliton source with fast and broad spectral tunability and nearly constant pulse width and average power. Solitons generated in a photonic crystal fiber, at the low power coupling regime, can be tuned in a broad range of wavelengths ranging from 850 nm to 1200 nm using the input power as the control parameter. These solitons keep almost constant time duration (∼ 40 fs) and spectral widths (∼20 nm) over the whole measured spectra regardless of input power. Our numerical simulations agree well with measurements and predict a wide working wavelength range and robustness to input parameters.
