Abstract: A method of making a photonic crystal includes step 1 providing a seed, followed by etching a surface of the seed to form thereon submicron voids; step 2 providing a graphite disk, followed by coating a side of the graphite disk with a graphite adhesive whereby the void-formed surface of the seed is attached to the graphite disk to form a seed holder; step 3 placing the seed holder above a growth chamber, followed by placing a raw material below the growth chamber; step 4 forming a thermal field in the growth chamber with a heating device to sublime the raw material; and step 5 controlling temperature, thermal field, atmosphere and pressure in the growth chamber to allow the gaseous raw material to be conveyed and deposited on the seed, thereby forming a photonic crystal.

Abstract: A micro driver includes a translational unit, an actuating unit and a rotational unit. The translational unit includes translational elements movable relative to one another. The actuating unit includes two opposite actuators connected to each of the translational elements. The actuators are operable to move the translational elements relative to one another. The rotational unit includes a frame and semi-spheres each located in an aperture defined in the frame and in contact with the uppermost one of the translational elements so that the uppermost translational element rotates the semi-spheres on the frame when the actuators causes the translational elements to move relative to one another.

Abstract: The present invention provides a multi-dimensional micro-actuator comprising a stator having a plurality of symmetrically arranged electrode piezoelectric plates, a rotator disposed near the stator, and a plurality of contacting elements. Each of the symmetrically arranged electrode piezoelectric plates comprises a piezoelectric plate, a first electrode, and a second electrode. The first and second electrodes are symmetrically arranged on a first surface of the piezoelectric plate. A second surface of the piezoelectric plate is coupled to the ground. The contacting elements are disposed on the electrode piezoelectric plates for rotation of the rotator.
