Abstract
Phase matched second harmonic generations (SHGs) in two kinds of poled polymer film waveguides are observed. Two kinds of dye dopants 2-methyl-4-nitroaniline (MNA) and Disperse Red 1 (DR1) are used for preparations of thin film poly-methylmethacrylate (PMMA) waveguides. The conditions for the collinear and the Cerenkov type phase matchings are realized at the thicknesses giving the same effective refractive indices for each type.
