Soliton-effect compression of supercontinuum to few-cycle durations in photonic nanowires

Abstract

By exploiting the broad region of anomalous group-velocity dispersion (GVD) and the large e.ective nonlinearity of photonic nanowires, we demonstrate soliton-e.ect self-compression of 70-fs pulses down to 6.8 fs. Under suitable conditions, simulations predict that self-compression down to single-cycle duration is possible.
