Abstract

We present experimental and theoretical details on how to analyze the polarization distribution in poled second order nonlinear optical polymers in three dimensions. The polar order can be analyzed in both the lateral and the vertical directions by scanning second harmonic microscopy (SSHM) at various wavelengths along the absorption tail of the polymer. Local thermal reorientation was accomplished using an Argon laser at a wavelength of 488nm, and the resulting change in polarization was analyzed by multi-(lambda) SSHM. We could demonstrate that the relative change in polarization is strongest at the surface that was irradiated with the Argon laser and decreases towards the opposite surface.
