Abstract

The mixing of two oppositely propagating guided wave beams in non-centrosym- metric media is known to generate a second harmonic line source traveling normal to the waveguide surfaces. 1~3 A number of signal processing applications such as pulse autocorrelation, wavelength demultiplexing, etc., have already been demonstrated in GaAs and LiNb03 waveguides.1-3 Here we report the first implementation of this SHG process in organic materials using a deff of 100 pm/V in a poled polymer film of 4-dimethylamino-4 '-nitrostilbene (DAN S) side chain molecules.4
