Soliton self-frequency shift in suspended core fibers

摘要

We experimentally demonstrate soliton self-frequency shifts well-beyond 500 nm in suspended core fibers. We compare two fibers and show that the dispersive wave generation induced by the presence of a second zero dispersion wavelength or the OH-absorption peak may limit the soliton shift performance. By measuring the frequency stabilization spectrum of the shifted soliton, we show that we can simply and accurately evaluate the second zero dispersion wavelength.
