PURPOSE: An optical modulator, a method for manufacturing and operating the same, and an optical device including a light modulator are provided to reduce volume by being vertically laminated in a semiconductor substrate for integration. CONSTITUTION: An optical modulator(100) comprises an electro-optics conversion element(20), an optics-electro conversion element, and a gate transistor(30). The electro-optics conversion element and the optics-electro conversion element are vertically laminated. The gate transistor gates signals transmitted from the optics-electro conversion element to the electro-optics conversion element. The optics-electro conversion element and the electro-optics conversion element, and gate transistor form unit pixels.
Abstract:
A two-axial drive MEMS device is provided to increase rotation driving force by two-axis driving caused by a first axis due to electromagnetic force and a second axis due to a difference of electromagnetic force. A two-axial drive MEMS device comprises a movable plate(100) coaxially supported with a first axis and driven about the first axis and a second axis perpendicular to the first axis, a stage(155) coaxially supported with the second axis inside the movable plate, a driving coil(110) including coaxial coil units(111a,111b) arranged along a line of the first axis of the movable plate and first and second connection coil units(115,115') connecting right and left end portions of the moving coil unit in an opposite position respectively, a pair of magnets(130) arranged closely to the first and second coil units so as to respectively form a magnetic field crossing the driving coil and a yoke magnetic material(180) arranged in an upper or lower portion of the magnets so as to enable the magnetic field to form magnetic flux density.
