摘要：

We report for the first time guided-wave second-harmonic generation in nonlinear optically active Langmuir-Blodgett (LB) films. Phase-matched frequency-doubling was observed in LB films of 2-docosylamino-5-nitropyridine (DCANP) by using the Cerenkov-type configuration. The charge transfer axis of the DCANP molecules essentially lies in a plane parallel to the dipping direction. Therefore the largest nonlinear optical coefficient d33 could be used by exciting TE modes propagating in the film. Gratings were used to couple light at lambda = 1064 nm into the LB film waveguide.
