Paper Abstract

We report for the first time phase-matched second-harmonic generation by mode conversion in nonlinear optically active Langmuir-Blodgett (LB) film waveguides. Phase-matched frequency- doubling was observed in LB films of 2-docosylamino-5-nitropyridine (DCANP) by conversion of a fundamental TE0-mode into a second-harmonic TE1-mode. The experiments were done in four-layer optical waveguides. For DCANP this four-layer configuration improves the theoretical conversion efficiency more than 100 times compared to a conventional three-layer waveguide. In the preliminary experiment infrared to blue light conversion efficiencies up to 0.5% W-1 cm-2 (0.02% W-1) were measured.
