Abstract: Microelectromechanical actuators include a substrate, spaced apart supports on the substrate and a thermal arched beam that extends between the spaced apart supports and that further arches upon heating thereof, for movement along the substrate. One or more driven arched beams are coupled to the thermal arched beam. The end portions of the driven arched beams move relative to one another to change the arching of the driven arched beams in response to the further arching of the thermal arched beam, for movement of the driven arched beams. A driven arched beam also includes an actuated element at an intermediate portion thereof between the end portions, wherein a respective actuated element is mechanically coupled to the associated driven arched beam for movement therewith, and is mechanically decoupled from the remaining driven arched beams for movement independent thereof. By allowing independent movement of the actuated elements, a variety of actuator applications may be provided wherein it is desired to actuate multiple elements in the same or different directions. For example, first and second driven arched beams may extend parallel to one another, such that the actuated elements that are mechanically coupled to the first and second driven arched beams move in a same direction by the further arching of the thermal arched beam. In other embodiments, the first and second arched beams arch away from each other, such that the actuated elements that are coupled to the first and second driven arched beams move in opposite directions by the further arching of the thermal arched beam. In yet other embodiments, the first and second driven arched beams arch toward one another, such that the actuated elements that are mechanically coupled to the first and second driven arched beams move in opposite directions by the further arching of the thermal arched beam.

Abstract: A set of mirrors (5,13) is arranged on a bottom substrate wafer (2) which is covered with a top substrate wafer (20). Several channels (38) are formed between protruding zones (34) present under the wafer (20). The protruding zones comprise housings (33) inside which the mirrors are movable. An Independent claim is also included for optical switching matrix fabrication method.

Abstract: The variable optical attenuator (1) is based on micro mechanical structures and has two moving walls (5,6) between optical fibres (3,4). The wall stops (7,8) are sloped with respect to the movement direction so as to form a V notch when approaching the optical fibres.

Abstract: The optical microswitch connects 4N optical inputs (I1n to I4n) with 4N optical outputs (O1n to O4n). There are five optical switch connections (S1 to S5) with 2N outputs. A group of four switches are connected together to generate 2N intermediate outputs and to a final output whilst a fifth structure provides the remaining outputs.

Abstract: The variable optical attenuator (1) comprises a microelectromechanical structure implemented on a substrate (2), including at least one shutter (31,33,34) whose position can be varied by an actuator with a mobile part (10) combined with the shutters in the form of beams with notches so that the shutter (31) interacts with a light beam (6) propagating from an input optical fibre (3) towards an output optical fibre (4). The mobile part (10) of the actuator can be displaced rotationally around an axis (11) perpendicular to the plane of the substrate, and the axis (11) is also an axis of rotational symmetry of the mobile part. The shutters are laid out in the thickness of the mobile part so to interact with the light beam (6) which propagates substantially in parallel with the rotational axis of the mobile part. The mobile part (10) of the actuator comprises several, in particular 3, zones (27) which cooperate with complementary zones (28) stationary with respect to the substrate, and the zones are distributed in angle around the rotational axis (11). In particular, the zones (27) are of electrostatic combs matching complementary combs of the stationary zones (28). The mobile part (10) is linked to a fixed central platform (24) situated at the center of gravity of the mobile part, and an application of a polarization voltage to the pairs of combs (27,28) causes a rotational motion including slight bending of beams (23) so that the shutter (31) intercepts the light beam (6) at the level of angular notch section. The middle beams (23) joined to the central platform (24) also serve to return the mobile part to its stationary position. The attenuator (claimed) functions by transmission, or by reflection when the shutter (31) comprises a reflecting part.

Abstract: Structure multicouche, utilisée notamment en tant que matériau de forte permittivité relative, caractérisée en ce qu'elle comporte une pluralité de couches distinctes, chacune d'une épaisseur inférieure à 500 .ANG., et réalisée à base de dioxyde d'hafnium (HfO2), de dioxyde de Zirconium (ZrO2) et d'alumine (Al2O3). En pratique, les couches de dioxyde d'hafnium, de dioxyde de Zirconium et d'alumine forment des alliages de formule Hf x ZrAl y O z. Avantageusement, la st~chiométrie des alliages Hf x ZrAl y O z varie d'une couche à l'autre.
