Abstract

The multimode interference inside a multimode fiber is used to design a tunable filter by utilizing a moving mirror in front of the fiber facet. Theoretical model is used to produce design curves for the center wavelength, filter bandwidth, tuning range, and the scanning range of the mirror. Experimental setups were performed to verify the theoretical results. A trade-off between the mirror scanning range and filter linewidth is found. Overall performance is observed to be better for smaller sections of multimode fibers, despite the difficulties encountered in handling (cleaving and splicing.)
