ELECTROOPTIC LIGHT-MODULATION AND 2ND-HARMONIC GENERATION IN NOVEL DIAZO-DYE-SUBSTITUTED POLED POLYMERS

Newly-synthesized methacrylate polymer containing a dicyanovinyl-terminated, dimenthyl-substituted diazo (3RDCVXY) dye has been developed for electrooptic device. The corona-poled 3RDCVXY polymer exhibits the largest chi(2) value of 1 x 10(-6) esu at 1.06-mu-m ever reported for poled polymer systems, whose thermal stability is excellent even at 80-degrees-C. The poled 3RDCVXY polymer film shows a linear EO coefficient as high as 40 pm/V at 0.633-mu-m. An electrooptical light modulation in the channel 3RDCVXY polymer waveguides with half-wave voltage as low as 5 V is obtained.
