摘要： A variable optical attenuator is disclosed. The variable optical attenuator includes an optical fiber part formed of at least one input optical fiber integrated with at least one output optical fiber, a mirror part having at least one micromirror facing into and spaced apart from the optical fiber part, reflecting emitted light rays emitted from the input fiber to the output fiber, and making one of a vertical movement and a rotational movement, so as to attenuate the emitted light rays, and a lens formed between the optical fiber part and the mirror part, and focusing the emitted light rays emitted from the input optical fiber to the micromirror.

摘要： A flow control valve apparatus using a flow control valve manufactured via micro-machining is provided. The flow control valve has a substrate defining at least one orifice through which a fluid can flow, a support member formed on a first surface of the substrate, at least one flap corresponding to the at least one orifice, a pair of elastic flexures connecting the support member to the at least one flap, and a driving means for displacing the at least one flap between the first and second positions to control fluid flow through the at least one orifice. The support member is formed adjacent to the at least one orifice and the at least one flap extends from the support member to fittingly engage the at least one orifice in a first and second position. Also, the pair of elastic flexures provides an elastic restorative force proportional to a displacement of the at least one flap between the first and second positions.
