Second-harmonic generation in photonic crystals with a pair of epsilon-negative and mu-negative defects.
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.
