Relative electrical resistivities and poling of nonlinear optical polymeric waveguides (original) (raw)

A method utilizing Maker fringe measurements was employed to assess the relative dc electrical resistivities of a range of linear and nonlinear optical polymers, particularly PMMA-PS copolymers. Findings highlight significant differences in resistivity levels, notably that PMMA exhibits an order of magnitude lower resistivity than PS. This technique aids in the identification of suitable low resistivity cladding materials essential for enhancing electric field poling efficiency in nonlinear optical polymeric waveguides.
