    Abstract: PURPOSE: A wavelength division multiplexer/demultiplexer is provided to prevent an interference phenomenon between neighboring channels by increasing and reducing the width of an input waveguide. CONSTITUTION: A wavelength division multiplexer/demultiplexer includes a grating for demultiplexing multiplexed optical signal to each channel, a plurality of input waveguides for inputting optical signals into the grating, and a plurality of output waveguides for outputting the demultiplexed channels. The input waveguide(413) of the wavelength division multiplexer/demultiplexer includes a first sub-waveguide and a second sub-waveguide. The width of the first sub-waveguide(413a) is increased along with the traveling direction of the optical signals. The width of the second sub-waveguide(413b) is reduced along the traveling direction of the optical signals passing the first sub-waveguide.

    Abstract: PURPOSE: A planar lightwave device having grating is provided to be capable of forming the accurate and uniform grating without using a phase mask, reducing a fabrication time, and realizing the reproducibility of a fabrication process. CONSTITUTION: A core layer(230) is formed on a semiconductor substrate(210), and an optical signal is issued through one end of the core layer. Lower and upper clads(220,250) are formed to surround the core layer. The core layer includes a lightwave part(232) and at least one or more grating parts(234,236). The lightwave part becomes a transfer path of the optical signal. Each of the grating parts is extended from one side of the lightwave part so as to filter a wavelength of the optical signal. A width of the extended part is varied periodically.

    Abstract: 본발명은불순물조성변화를이용한도파로의변형및 잔류응력감소를통하여복굴절을제거한광도파로제작용기판및 그제작방밥에관한것으로, 이러한광도파로제작용기판은기판, 기판과인접한부분은불순물의함유량이증가되어형성되고, 코아층과의인접한부분은불순물의함량이조절되어코아층과의소정의굴절율차를갖도록형성된하부클래드층및 하부클래드층위에광도파로패턴이형성된코아층을포함함을특징으로한다. 본발명에의하면, 실리콘기판과인접한하부클래드층은불순물유량을증가시켜증착함으로써불순물함유량을증가시켜실리콘기판과의열팽창계수차이및 소결후기판냉각시하부클래드층의유리화온도와주변온도와의차를줄여실리콘기판의변형을막고더불어잔류응력을최소화시켜유도복굴절을제거할수 있다. 또한하부클래드층증착시불순물유량조절을통한하부클래드층의조성변화를이용하므로버퍼층을추가하는방법과는달리버퍼층증착및 소결공정이필요하지않는장점이있다.

    Abstract: PURPOSE: An optical waveguide having linear layers through which optical signals pass and its anufacturing method are provided to remove a birefringence by changing impurities on a cladding layer. CONSTITUTION: A substrate comprises a SI substrate layer(210), a core layer(230), and a cladding layer(220). A core layer is formed on a lower cladding layer where an optical waveguide is formed. A cladding layer formed on a planar substrate layer contains impurities to decrease a difference of a thermal expansion coefficient between a SI substrate and a cladding layer. A cladding layer has a different refractive index between an upper part and a lower part by injecting impurities into a SI substrate. As decreasing a sintering temperature during an inject on process, it prevents a substrate deformation and decreases a residual stress.
