Abstract
A fiber-attached optical device with in-plane micromachined mirrors includes a cover having at least one reflector formed on one side and a substrate having a plurality of micromachined optical mirrors formed substantially on a single plane on a side facing toward the mirrored side of the cover. The micromachined optical mirrors are controllable to reflect optical signals between a plurality of optical fiber segments via the at least one reflector. The plurality of optical fiber segments can be attached to either the cover or the substrate so as to form an integrated package including the substrate, the cover, and the plurality of optical fiber segments. The mirrors can be controlled to variably attenuate the optical signals.
