Abstract
A micro-aligner for precisely aligning an optical fiber with an optical device, and methods of making and using same. The micro-aligner includes a carrier having a surface plane and holds an optical fiber to be positioned in alignment with an optical device. Spring biased first and second microactuators are provided on the carrier for effecting in-plane movement and alignment of the optical fiber with an optical device in either or both of two orthogonal in-plane directions when either or both of said in-plane microactuators is activated. Backstops are located on the carrier in respective association with each of the first and second microactuators, respectively, such that the first and second backstops delimit the amount of return in-plane movement of the respective beam after either of the respective first or second microactuator is de-activated. A third microactuator also is provided on the carrier which, when activated, effectively deflects the carrier upward in a direction away from the base.
