METHOD AND APPARATUS FOR OPTICALLY ALIGNING OPTICAL FIBERS WITH OPTICAL DEVICES

摘要

An automatic fiber pigtailing machine (AFPM) is disclosed. The AFPM provides precise coupling between a fiber pigtail (358) and an optoelectronic (OE) device (352) based on the fidelity of signal transfer across a junction between the fiber (358) and (OE) device (352). The AFPM uses a positioning system with a high frequency closed loop optical feedback of a modulated signal to/from the device under assembly (DUA). Local/global maximums in the fidelity of the modulated signal are correlated with relative orientations/alignment/positions of the various components of the DUA to determine the preferred orientation/alignment/positions between the various components for the completed assembly.
