Optical Assembly of Collimator Arrays for MEMS Applications

摘要

In the collimator array development effort for MEMS applications, the ability to align devices automatically that meets industry target specifications of power throughput for multiple channels has been demonstrated. Results show eight-channel devices have been successfully aligned and attached within 2dB power loss. Three key factors of success include: (1) Automated Pitch/Yaw using virtual pivot, (2) initial mirror alignment to verify parallelism between fiber array and lens array, (3) channel balance algorithm to compensate for lens array pitch and focal length variations.
