Abstract
We improve the beam uniformity passing through multimode fibers using piezoelectric-based spatial mode scrambling. Both fiber squeezing and stretching techniques are applied and compared. A more than sixfold difference in the power intensity crossing the output beam profile without mode scrambling can be reduced to a <10% variation. The efficiency of collecting useful optical power for detection is also significantly improved. Such modules can find various applications in medical imaging, disease diagnosis, and local area networks.
