Abstract
We have realized quasi-phase-matched second-harmonic generation by usi ng a planar waveguide consisting of periodical ridge-shaped crystals o f 2-methyl-4-nitroaniline (MNA). The largest nonlinear optical coeffic ient d(11) of MNA was used. The quasi-phase matching was attained by a ngle tuning to coherence lengths corresponding to conversions from fun damental TE(0) and TE(2) modes into second-harmonic TE(10) and TE(12) modes, respectively.
