초록
The present invention relates to the polarization-independent optical polymeric intensity modulator independent of input signal using polymers with electro-optical property. To use the electro-optical property for electro-optical polymer, polymers must be poled by applying high voltage to the waveguide. The size of phase modulation caused by such an poling varies from the biggest value at polarization parallel to the poling to the smallest value at polarization perpendicular to the poling. Therefore, the performance of the electro-optical polymeric intensity modulator depends on the polarization state of input light. The present invention provides the polarization-independent optical polymeric intensity modulator capable of modulating the optical intensity without regard to the polarization of the input signal by making the polarizing directions of two optical paths of M-Z interferometer perpendicular each other.
