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 wireless power transmission device and method for reducing radiated power of a magnetic resonator are provided to transmit energy by selecting a frequency having relatively low radiated power. CONSTITUTION: A signal generator(102) generates a frequency signal used for wireless energy transmission from general commercial AC powder. A power amplifying unit(104) amplifies the frequency signal. A signal detection unit(106) transfers the amplified signal to a magnetic resonator for wireless energy transmission and detects a radiated signal caused by the magnetic resonator. A standing-wave ratio calculation unit(108) calculates a standing-wave ratio from the detected signal. A control unit selects the frequency having the lowest standing-wave ratio using the standing-wave ratios calculated by the standing-wave ratio calculation unit.

Abstract: PURPOSE: A manufacturing method of a micro vertical structure is provided to improve the performance of an MEMS device such as an electrostatic sensor and an optical element by minimizing form defects and footing phenomenon. CONSTITUTION: An insulating layer pattern(220a) and a hollow space are formed in order to prevent footing phenomenon by patterning an insulating layer(220) after forming the insulating layer on a first crystalline silicon substrate. After welding a second crystalline silicon substrate(230) on the dielectric layer pattern, the second crystalline silicon substrate is etched through a deep reactive ion etching method along the crystal plane of the vertical direction to the second crystalline silicon substrate. A micro vertical structure(230a) with a side vertically to the second crystalline silicon substrate is formed by etching the etched side surface of the second crystalline silicon substrate through a crystalline wet etching method.
