摘要： A tunable laser comprising a laser source for providing light with a wavelength along an optical path. A diffractive element is positioned in the optical path and spaced from the laser source for redirecting the light received from the laser source. A reflective element is positioned in the optical path and spaced from the diffractive element for receiving the light redirected by the diffractive element and for further redirecting the light back along the optical path to the reflective element. The diffractive element receives the light further redirected by the reflective element and returns the light along the optical path to the laser source. The optical path created by the laser source, the diffractive element and the reflective element causes the light to lase at the wavelength. At least one microactuator is coupled to one of the diffractive element and the reflective element for moving such element to select the wavelength of the light. A variety of microactuators that can be used with the tunable laser are provided.

摘要： A balanced microdevice comprising a substrate, a movable structure overlying the substrate, an element and a lever assembly having a pivot and a lever coupled to and pivotable about the pivot. The lever has a first extremity coupled to the movable structure and an opposite second extremity coupled to the element. The movable structure causes the lever to pivot about the pivot so as to move the element in a direction of travel. The element is substantially mechanically balanced to inhibit undesirable movement of the element in the direction of travel in response to externally applied forces.

摘要： Micro-machined tools and component holders useful for the manufacture, assembly, and testing of precision micro-miniature parts are provided, particurlarly embodiments well adapted for precision micro-miniature systems incorporating optical and/or electronic components including lenses, optical fibers, and the like. Structure and method find particular applicability in the precision optical systems of the read, write, or read/write heads of optically assisted storage devices for digital computers. Removable tools are used to temporarily position components while the components are glued or otherwise fixed into place during assembly, and then completely removed for use with another head assembly. Break-away tools or holders typically include three major portions: an element holder, a handle, and a break-away neck portion connecting the holder with the handle. The element holder provides a mounting block for an optical, electrical, or mechanical element. Once the elements are attached to the mounting blocks, they are moved into position within the larger assembly via the handle, the mounting block is glued to the assembly and a small predictable force is applied to the handle to break the neck and separate the handle from the holder which is at that time attached to the assembly. Tools may be formed by photolithographically patterened and etching a substrate such as silicon to selectively carve the substrate. Structures formed from plated metal, either on a base material, or made entirely of metal are also provided by the invention. Several embodiments of process for forming the inventive structures are also provided.
