Publication number: 20140090471Abstract: An inertial measurement device and method for measuring acceleration in three axes. Three orthogonally disposed accelerometers are defined on a common planar substrate. At least one of the accelerometers is provided with a proof mass coupled to a nano-resonator element. The nano-resonator element is oscillated at a first predetermined frequency, which may be a first resonant frequency, and is altered to oscillate at a second frequency, which may be a second resonant frequency, in response to a resultant force produced by the acceleration of the proof mass. The degree of change in nano-resonator element output frequency is sensed and processed using suitable processing circuitry as a change in acceleration on the active axis.Type: ApplicationFiled: October 18, 2013Publication date: April 3, 2014Inventor: Ying Wen Hsu

Patent number: 7003188Abstract: An optical switching system that switches the path of an optical signal by moving a microstructure onto which a light-guiding structure is mounted. The microstructure is formed by a MEMs and semiconductor process to be integral to the substrate. The light-guiding structure may include waveguides. The microstructure moves from one position to another position (e.g., laterally, vertically, rotationally) such that incoming optical signals align over a small air gap to different optical paths, depending on the position of the movable microstructure. As a result, the optical signal propagate along different optical paths (e.g., straight pass through or cross over) depending on the position of the movable microstructure. The optical paths have a large radii of curvature so as to change the direction of the optical signal gradually, thereby reducing insertion losses.Type: GrantFiled: September 30, 2003Date of Patent: February 21, 2006Inventors: Ying Wen Hsu, Arthur R. Telkamp

Patent number: 6990264Abstract: A 1×N or N×1 optical switch based on a plurality of movable MEMS-created platforms, each carrying a light guiding structure such as a waveguide, where the position of the platforms determines which optical path is connected through the optical switch. The MEMS-created platforms are formed integral with the substrate of the optical switch. The waveguides residing on the movable platforms gradually change the direction of the optical signal in order to minimize losses. The movable platforms can move linearly or rotationally, for example. Also described is a method for fabricating such an optical switch and its components by etching from the bottom of the substrate and through the oxide.Type: GrantFiled: October 19, 2001Date of Patent: January 24, 2006Inventors: Arthur R.

Patent number: 6954579Abstract: An improved device, which may act as a variable attenuator, changes the optical intensity of an optical signal by moving a platform onto which a light transmissive structure such as a waveguide is disposed. The light transmissive structure is positioned and aligned to receive an optical signal and positioned and aligned to transmit the optical signal. By moving the light transmissive structure into a position of reduced alignment with an input source, the light transmissive structure may receive less or none of the optical signal, thereby attenuating it. Alternatively, by moving the light transmissive structure into a position of reduced alignment with an output structure, the light transmissive structure may transmit less or none of the optical signal, thereby attenuating its transmission.Type: GrantFiled: November 29, 2001Date of Patent: October 11, 2005Inventor: Ying Wen Hsu

Patent number: 6836583Abstract: Numerous novel structures and methods are presented for their ability to correct angular and offset alignment errors caused by thermal distortion of a device formed out of dissimilar materials, such as a movable platform and waveguide coupled to a fixed platform and another waveguide. A flexure connected between two platforms corrects offset alignment errors along the centerline axis of the flexure. Thermal distortion is corrected also by varying the relative size of the two platforms and the addition of slots and/or extraneous waveguides. A waveguide may be sandwiched between two matching materials, with or without an extra thermal compensation layer portion. A method uses simple processes to build a substrate with matching waveguides on each side of the substrate. Another simple method creates a suspended structure by using simple semiconductor processes.Type: GrantFiled: March 30, 2004Date of Patent: December 28, 2004Assignee: Newport Opticom.
