摘要：

Frequency doubling of infrared coherent radiation in a planar waveguide loaded by an organic thin film is described. By using a strongly nonlinear crystal, such as 2-methyl-4-nitroaniline, as the loading organic material, more second-harmonic radiation can be expected than that reported in a proton-exchanged or Ti-diffused LiNbO3 waveguide. The electromagnetic field analysis shows that the selection of a cover material that bounds the surface of the organic film is important in fulfilling the Čerenkov condition. © 1990 Optical Society of America.
