Abstract: PROBLEM TO BE SOLVED: To provide an optical element with an integrated light deflector with which a light direction is deflected without requiring a complicated external driving circuit. SOLUTION: A manual waveguide having the light deflector integrated therewith is equipped with cladding regions 301, 304, an optical waveguide core 302 and the light deflector 303. A propagation direction of light waveguided to the optical waveguide core 302 is varied in passing of the light through the light deflector 303. The light deflector 303 is formed by patterning a part of the upper cladding layer on the upper side of a specified region of the optical waveguide core 302 in a predetermined shape and deflects the propagation direction of the advancing light by modifying the refractive index of the core 302 on the lower side of the predetermined shape in accordance with a current or an electric field applied to the light deflector 303.

Abstract: PROBLEM TO BE SOLVED: To provide a variable wavelength external resonator which can vary the wavelength by an electric signal, can successively very a wavelength at high speed, and uses a light deflector stably operating according to the electric signal. SOLUTION: A light beam emitted from a light source 301 is transformed to a parallel light beam by a lens 302a. The parallel light beam is diffracted on a diffraction grating 304, and is propagated through a light deflector 308 arranged between a reflecting mirror 305 and the diffraction grating 304. The light deflector 308 is configured so that an index of refraction can vary according to an input electric signal. Of light beams propagating through the light deflector 308, only a light beam with a specific wavelength is emitted perpendicularly to the reflecting mirror 305. Thus, the light beam with the specific wavelength is refocused on the light source 301. COPYRIGHT: (C)2003,JPO

Abstract: The present invention relates to an optical deflector driven by an electrical signal, and a wavelength unable external resonator using the same . The optical deflector of a triangle shape, capable of controlling the refractive index of a beam depending on the electrical signal, is positioned between a reflection mirror and a diffraction grating in a Littman-Metcalf mode extern al resonator or between a lens and the diffraction grating in a Littrow mode external resonator. Thus, even with the reflection mirror and the diffractin g grating fixed, the refractive index of the beam generated from a laser diode can be controlled by adjusting the electrical signal applied to the optical deflector, so that beam having a specific wavelength can be focused and the wavelength can be rapidly and consecutively tuned.

Abstract: PURPOSE: A system, a device, and a method for transferring data are provided to transfer data between one user process and a kernel at a proper time. CONSTITUTION: A data transfer system includes a user process region(100), a kernel region(200), and a hardware region. User processes are executed in the user process region. The kernel area comprises a kernel thread(240). The hardware region performs input/output according to an input/output request of each user process. When the user process is being executed, the kernel thread copies input data to the user process region from the kernel region.
