Patents by Inventor Terry D. Zhu

Terry D. Zhu has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • MEMS optical switches having obliquely angled inputs and outputs relative to a face thereof and moveable reflectors with parallel positions therein and methods of forming same
    Patent number: 6636655
    Abstract: MEMS optical switches can include a substrate having first and second opposing faces and at least one side therebetween. An input is obliquely angled towards the face and optically couples optical radiation towards the face. A movable reflector is on the face and moves from a first position to a second position that is parallel to the first position to reflect the optical radiation from the input to provide reflected optical radiation. A output is obliquely angled away from the face and optically couples the reflected optical radiation away from the face.
    Type: Grant

  • Optical switches including reflectors having associated actuators and latches located adjacent to a surface thereof and methods of operating same
    Publication number: 20030095741
    Abstract: Embodiments of the present invention can provide a substrate and a moveable reflector, on the substrate, having first and second opposing surfaces, wherein the moveable reflector moves to first and second positions on the substrate. A latch is located on the substrate adjacent to the first surface of the moveable reflector opposite the second surface and coupled to the moveable reflector, wherein the latch holds the moveable reflector in the first and second positions. An actuator is located on the substrate adjacent to the first surface of the moveable reflector opposite the second surface and is coupled to the latch, wherein the actuator moves the moveable reflector to the first and second positions.
