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.

摘要： Provided is an optical coupler. The optical coupler includes a lower cladding layer on a substrate, a core layer on the lower cladding layer, the core layer comprising a diffraction grating coupler and an optical waveguide, and an upper cladding layer on the core layer. The upper cladding layer has a thickness of about one quarter of a wavelength of an optical signal passing through the core layer divided by a refractive index of the first upper cladding layer. Thus, Fresnel reflection may be minimized, and also, it may prevent a Fabry-Perot interferometer from occurring.

摘要： An interband resonant tunneling intersubband transition laser is disclosed, and includes a semiconductor substrate, and a first cladding layer, an active region structure layer and a second cladding layer formed on the semiconductor substrate. The active region structure layer includes quantum well layers and quantum barrier layers that are alternately stacked and have a broken energy bandgap. Thus, the interband resonant tunneling intersubband transition laser operates in a cascade mode in which an intersubband radiative transition and interband tunneling of carriers consecutively and repetitively occur in the active region structure layer, and thus can achieve a high output from a simple, compact structure.
