  • Title: Second-harmonic generation in photonic crystals with a pair of epsilon-negative and mu-negative defects.
    Author: Du QG, Ren FF, Kam CH, Sun XW.
    Journal: Opt Express; 2009 Apr 13; 17(8):6682-7. PubMed ID: 19365495.
    Abstract:
    A conventional one-dimensional photonic crystal with a conjugated pair of epsilon-negative and mu-negative defects has been presented, and only the defects are presumed to possess quadratic nonlinearity. Large enhancement of second-harmonic generation is predicted in numerical simulation. Interface and volume nonlinearity are both utilized in the process of second-harmonic generation due to the strong localization of the fundamental wave.
