| Abstract: | Second-order optical nonlinearity of a disazo dye attached polymer was investigated. The optical loss of the film is 1.5 dB/cm at 633 nm. The second-order nonlinear coefficient chi /sup (2)/ of the poled film is comparable to that of lithium niobate at 1.55 mu m. The chi /sup (2)/ is greater than that of a monoazo dye attached polymer throughout the fundamental wavelength of 1.06-1.70 mu m.<> |
