    Abstract: An optical filter module for wavelength multiplexing and demultiplexing and a method of manufacturing the same are provided. The optical filter module for wavelength multiplexing and demultiplexing includes: at least one or more input waveguides; an input-stage star coupler in the form of a slab waveguide connected to the input waveguides; array waveguide which is connected to the input-stage star coupler and in which a plurality of individual waveguides, each of which has an optical path having a predetermined length different to those of the other waveguides and has a heterogeneous waveguide interval formed of a material having a different refraction index from that of a core of the waveguides, are sequentially arranged; an output-stage star coupler in the form of a slab waveguide connected to the array waveguides; and at least one or more output waveguides connected to the output-stage star coupler. According to the optical filter module and the method of manufacturing the same, heterogeneous waveguide intervals having core materials different from those of conventional waveguides are introduced in predetermined areas of array waveguides, thereby reducing polarized light and temperature dependency and at the same time effectively removing optical coupling loss, which can occur at both ends of a heterogeneous waveguide interval, without an additional process of forming waveguides.

    Abstract: 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.

    Abstract translation: 本发明涉及不依赖于具有电光学性质的聚合物的输入信号的偏振非依赖光学聚合物强度调制器。 为了将电光学性质用于电光聚合物，聚合物必须通过向波导施加高电压来极化。 由这种极化引起的相位调制的大小从垂直于极化的偏振极化时的平行极化极化的最大值变化到最小值。 因此，电光聚合强度调制器的性能取决于输入光的偏振状态。 本发明提供了通过使M-Z干涉仪的两个光路的偏振方向彼此垂直而能够调节光强度而不考虑输入信号的偏振的偏振无关的光聚合强度调制器。
