  • Title: Parametric gain in dispersion engineered photonic crystal waveguides.
    Author: Willinger A, Roy S, Santagiustina M, Combrié S, De Rossi A, Cestier I, Eisenstein G.
    Journal: Opt Express; 2013 Feb 25; 21(4):4995-5004. PubMed ID: 23482032.
    Abstract:
    We present a numerical simulation of parametric gain properties in GaInP PhC dispersion engineered waveguides in which the group velocity dispersion crosses zero twice and where the pump and the signal are 100 ps pulses. The simulations use the M-SSFT algorithm which incorporates dispersive nonlinear coefficients and losses. We concentrate on narrow band parametric gain which occurs for pump wavelengths in the normal group velocity dispersion regime. The effects of structural details, of pump wavelength and of losses are carefully analyzed.
