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.

摘要： An integrated optical intensity modulator and a method for fabricating it. The integrated optical intensity modulator includes a substrate having spontaneous polarization, cut in an axial direction; an optical waveguide on the substrate; domain-inversion areas having domains reverse from the direction of spontaneous polarization, arranged in a staggered pattern around the optical waveguide; a first electrode on the optical waveguide on a surface of the substrate, and second and third electrodes on the substrate on opposite sides of and on the same surface as the first electrode. When a voltage is applied to the first electrode, a light wave is deflected and scattered in a domain-inversion area in accordance with a change of the refractive index of the domain-inversion area in the optical waveguide and the refractive index of the spontaneous polarization area. Since the domain-inversion structure of the ferroelectric substrate has a staggered pattern around the optical waveguide, and an optical guided mode is deflected by an applied voltage, only half the driving voltage of prior art structures is required for the optical waveguide. Deflecting the optical guided mode to the right and to the left alternatively, in multiple stages, increases the extinction ratio.
