摘要： A spatial switch of a simple structure using a "M.times.N" optical beam steering device which operates with M "1.times.N" spatial switches using a phased optical waveguide array. The spatial switch using an optical beam steering device in accordance with the present invention is characterized in that the optical beam steering device includes an optical waveguide phase modulator array, the optical beam steering device is used as a "1.times.N" spatial switch device, and M units of the "1.times.N" spatial switch device are aligned in parallel so that a "M.times.N" spatial switching operation is performed on a plane where a far field diffraction pattern of the "1.times.N" spatial switch device is formed. The spatial switch utilizes the characteristics that if the propagation directions of the lights output from "1.times.N" switches coincide with each other, the far field diffraction patterns formed by the switches converge into the same point.

摘要： An electro-optic polymer waveguide device capable of decreasing a driving voltage and an optical loss is disclosed. A vertical tapered waveguide is formed between passive waveguides of input and output portions in a waveguide and an electro-optic modulating region, and an amplitude of a waveguide mode of the input and output portion waveguide is equal to that of a optical fiber, thereby minimizing a connection loss with the optical fiber.

摘要： A method of fabricating a thermooptic tunable wavelength filter of optical communication systems using WDM is provided, which includes the steps of forming a polymer optical waveguide on a semiconductor substrate using a polymer material, forming a polymer Bragg grating on the optical waveguide using O2 RIE and polymer spin coating, and forming a thermooptic tuning electrode over the polymer optical waveguide in which the Bragg grating is integrated. This provides the thermooptical tunable wavelength filter which has very narrow wavelength band width of transmission signal, low crosstalk with optical signals adjacent thereto, stable wavelength tuning characteristic using thermooptic effect and wide tuning ranges. Furthermore, the optical devices using the polymer optical waveguide can be fabricated with low cost. Thus, they have advantages in terms of economy and marketability.
