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.
