Measuring electro-optic coefficients of poled polymers iusing fiber-optic mach-zehnder interferometer

It is proposed and demonstrated that fiber-optic Mach-Zehnder interferometer measures accurately the EO coefficients of, not only the poled polymer thin film, but also the poled polymer waveguide. Furthermore, the tensor components, both r
₁₃
and r
_r33
, of EO coefficient can be measured simultaneously.
