Abstract: A micro-electro-mechanical-system (MEMS) mirror device and methods for fabricating the same allow for a large range of angular motion for a center mirror component. The large range of angular motion for a center mirror component is dictated simply by a thickness of a substrate used or a thickness of a thick film used in making a support structure to support the center mirror component. The MEMS mirror device and methods for fabricating the same allow a large number mirror devices to be fabricated on a substrate. The MEMS mirror device includes a substrate. Electrodes are formed supported by the substrate. A support structure is formed adjacent to the electrodes. A hinge pattern and a mirror pattern having a center mirror component are formed such that the support structure supports the hinge pattern and mirror pattern. The support structure also supports the hinge pattern and mirror pattern such that a bottom surface of the center mirror component in a stationary non-rotating position is capable of exceeding a height of 50 mum above the electrodes.

Abstract: An optical switch having switch mirror arrays controlled by scanning beams that reduce the amount of electrical connections required and reduce the complexity for constructing large optical switches. Movement of the switch mirror arrays is controlled by one or more scanning beams. The optical switch includes one or more arrays of optical switch inputs and outputs and one or more arrays of movable mirrors to direct light beams from the optical switch inputs to the optical switch outputs. The optical switch also includes one or more control elements to control the movable mirrors based on scanning beams directed to the one or more control elements.

Abstract: An optical switch is described having mirrors that are located over an area having an approximate oval shape. Each mirror is pivotable about a first axis and about a second axis transverse to the first axis. Because of the construction and assembly of each mirror, pivoting about the first axis is more limited than pivoting about the second axis. The area over which the mirrors are located is designed to accommodate pivoting about the first axis and about the second axis such that the area has a length and a width wherein the length is much more than the width. In addition, pivoting about the first axis limits pivoting about the second axis and pivoting about the second axis limits pivoting about the first axis.

Abstract: A micromachined apparatus for reflecting light is described that is designed to reduce losses in quality or intensity of light. Mirrors are used having lengths that are longer than their widths to reduce clipping of light when a mirror is located at an angle with respect to light falling thereon. Relatively long mirror torsion components are used to reduce forces required to pivot the mirrors. Regardless of the dimensions of the mirrors and the use of long torsion components, the mirrors are still located relatively close to one another. The relatively close positioning of the mirrors is due to a combined use of notches formed in support frames to which the torsion components are secured, oval shapes of the mirrors which take up less space than rectangular shapes, matching oval openings in the support frames, and the arrangement of the suport frames in a non-rectangular array wherein tips of the support frames are located between one another.
