Abstract
An active alignment photonics assembly actively couples optical energy between optical devices. An adjustable fiber or other optical carriers, carries an optical signal which is received at a detector where the power level of the optical signal is measured. Based on the power level measurement, the alignment of the fiber or other optical devices contained in the assembly are provided by an optical feed-back loop which controls the position of the fiber or other devices relative to the detector by use of microactuator mechanisms.
