The optical waveguide device for loss absorption includes: a substrate of a predetermined material; a lower cladding formed on the substrate; an optical waveguide formed on the lower cladding, and formed of a material having a refractive index greater than a refractive index of the lower cladding; an upper cladding formed so as to completely cover the optical waveguide; and an absorption layer formed of a material having refractive index greater than a refractive index of the upper cladding, and formed on the upper cladding to a thickness which can absorb a reflected or radiated optical signal. As described above, an absorption layer capable of absorbing light is formed in the waveguide device upon fabricating the optical waveguide, thus minimizing or removing loss due to reflection and radiation of an optical signal.

摘要： An optical power divider using a beam separator and a beam expander, and a fabrication method therefor. The optical power divider includes an input optical waveguide having an input port for receiving incident light, for guiding the light incident via the input port, a plurality of output optical waveguides having at least two output ports, for outputting the light incident via the input optical waveguide to the output ports, wherein the number of output optical waveguides is equal to that of the output ports, and a beam separator located at a branch area in which the light incident on the input optical waveguide diverges toward the output optical waveguides, the beam separator being made of a material having a refractive index lower than the core of the input and output optical waveguides, for separating the light to the output optical waveguides with a predetermined ratio. Therefore, the length of the optical power divider becomes short and insertion loss can be lowered. Also, an optical power divider for the special application, providing different splitting ratios between inner and outer output ports, can be easily designed by controlling the lengths of a side of each beam separator and beam expanders, and the splitting ratio of the output optical power of the optical power divider can be controlled. Also, the cost of fabricating the optical power divider can be reduced.

摘要： A method of fabricating a planar optical waveguide in one chamber, comprising the steps of depositing a cladding layer and a core layer on a substrate, depositing an etch mask layer on the core layer, and forming a photoresist pattern on the etch mask layer. An etch mask pattern is formed by etching the etch mask layer according to the photoresist pattern using a first gas which reacts with the material of the etch mask layer, and removing the first gas. An optical waveguide is formed by etching the core layer according to the etch mask pattern using a second gas which reacts with the material of the core layer in the same chamber as the chamber where the above steps were performed, and removing the photoresist pattern and the second gas. The etch mask pattern is removed using the first gas which reacts with the material of the etch mask pattern in the same chamber as the chamber where the above steps were performed, and removing the first gas, and depositing an upper cladding layer formed of the same material as the core layer on the resultant structure of the above step. Accordingly, processes for fabricating an optical waveguide can be continuously performed in one chamber, thus simplifying and automating the optical waveguide fabrication method.
