Abstract
Second harmonic generation (SHG) in planar nonlinear waveguides is investigated under conditions for which the use of a linear grating fabricate don top of the waveguide reproduces a photonic band-gap structure. The fundamental mode of the guide, at the fundamental frequency, is tuned at the photonic band edge resonance thus experiencing a great confinement and enhancement of the electromagnetic field inside the structure. The linear grating alone is however not able to produce both field confinement and phase- matching of the SHG process. Phase-matching is obtained by an additional modulation of the non linear susceptibility (chi) (2), as in the conventional quasi-phase-matching scheme. The conversion efficiency achieved using both linear and nonlinear gratings is orders of magnitude greater than that of a quasi-phase-matched device of the same length.
