    Abstract: A display apparatus comprises a modulator for selectively interacting with light in an optical path to form an image on the display apparatus. A controllable first electrostatic actuator provides a first mechanical support for the modulator, the first mechanical support providing a supportive connection from a first location on the modulator to a surface over which the modulator is supported. A second mechanical support provides a supportive connection from a second location on the modulator to the surface. The first electrostatic actuator drives the modulator in a plane substantially parallel to the surface.

    Abstract: In embodiments of the present invention, a microelectromechanical actuator includes a beam having respective first and second ends attached to a substrate and a body disposed between the first and second ends having a sinuous shape. The body includes a portion operative to engage a object of actuation and apply a force thereto in a direction perpendicular to the beam responsive to at least one of a compressive force and a tensile force on the beam. The sinuous shape may be sinusoidal, e.g., a shape approximating a single period of a cosine curve or a single period of a sine curve. The beam may be thermally actuated or driven by another actuator. In other embodiments, a rotary actuator includes first and second beams, a respective one of which has first and second ends attached to a substrate and a body disposed between the first and second ends. Each body includes first and second oppositely inflected portions. The bodies of the first and second beams intersect one another at points at which the first and second oppositely inflected portions of the first and second bodies meet. The bodies of the first and second beams are operative to engage the object of actuation and rotate the object of actuation around the point of intersection responsive to at least one of compressive force and tensile force on the first and second beams. Related methods are also described.

    Abstract: A MEMS (Micro Electro Mechanical System) variable optical attenuator is provided that is capable of optical attenuation over a full range of optical power. The MEMS variable optical attenuator comprises a microelectronic substrate, a MEMS actuator and an optical shutter. The MEMS variable optical attenuator may also comprise a clamping element capable of locking the optical shutter at a desired attenuation position. The variable light attenuator is capable of attenuating optical beams that have their optical axis running parallel and perpendicular to the substrate. Additionally, the MEMS actuator of the present invention may comprise an array of MEMS actuators capable of supplying the optical shutter with greater displacement distances and, thus a fuller range of optical attenuation. In one embodiment of the invention, the MEMS actuator comprises a thermal arched beam actuator. Additionally, the variable optical attenuator of the present invention may be embodied in a thermal bimorph cantilever structure. This alternate embodiment includes a microelectronic substrate and a thermal bimorph cantilever structure having at least two materials of different thermal coefficient of expansion. The thermal bimorph is responsive to thermal activation and moves in the direction of the material having the lower thermal coefficient expansion. Upon activation, the thermal bimorph intercepts the path of the optical beam and provides for the desired level of optical attenuation. The invention also provides for a method of optical attenuation and a method for fabricating an optical attenuator in accordance with the described structures.
