Abstract
A method is disclosed by which precision alignment of optical fiber to wave-guide or other optical elements can be carried out with an adjustable microstructure in active alignment mode fiber attachment. A microstructure containing three elongated U-grooves can be combined effectively to produce a movable and adjustable V-groove structure, which can be used to achieve sub-micron scale alignment control with zero rotational torque. This device not only makes fiber alignment easy and fast but also maintains the fiber attachment position after alignment and epoxy bonding. Multiple fiber array alignment can be carried out with only a global alignment of two end fibers.
