Ultrafast-pulse self-phase modulation and third-order dispersion in Si photonic wire-waveguides


, : Ultrafast-pulse self-phase modulation and third-order dispersion in Si photonic wire-waveguides. Optics Express 14(25): 12380-7

By propagating femtosecond pulses inside submicron-crosssection Si photonic-wire waveguides with anomalous dispersion, we demonstrate that the pulse-propagation dynamics is strongly influenced by the combined action of optical nonlinearity and up to third-order dispersion with minimal carrier effects. Because of strong light confinement, a nonlinear phase shift of a few pi due to self-phase modulation is observed at a pulse peak-power of just ~250 mW. We also observe soliton-emitted radiation, fully supported by theoretical analysis, from which we determine directly the third-order dispersion coefficient, beta(3) = -0.73 +/- 0.05 ps(3)/m at 1537 nm.

The aim of this study was to examine the possible role of certain hormones (especially hydrocortisone) in the developmental variations of intestinal fucosyl-transferase activity in rats. Thyroxine and insulin, injected into suckling rats, did not...
