We investigate experimentally resonant radiation processes driven by slow solitons in a dispersion engineered photonic crystal waveguide in a regime virtually free of dissipative nonlinear processes (two-photon absorption and Raman scattering). Strong (30% energy conversion) Cherenkov-like radiation accompanied by the blue self-frequency shift of the soliton is observed close to the zero dispersion point,and is explained in terms of the soliton-radiation locking of the velocity
