Abstract: We report the high-energy flat-top supercontinuum covering the midinfrared wavelength range of 1.9-2.5 μm as well as electronically tunable femtosecond pulses between 1.98 and 2.22 μm ...

Abstract: We design a silicon nanowire embedded spiral photonic crystal fiber exhibiting a flattened, anomalous with small third order dispersion and a high nonlinearity and demonstrate supercontinuum ...
