The Three Stub Alignment Method for Maximizing Transmission Through Optical Fiber Junctions.

摘要

The three rod alignment technique which has been utilized for splicing and connecting fibers, has been adapted to make a fiber coupler which produces an error signal when there is offset in the fiber junction. Proper interpretation of this error signal allows the junction to be adjusted to zero offset, thus maximizing the power transmitted through the junction. This thesis discusses light propagation in optical fibers, the structure of optical fibers, distributed and misalignment loss mechanisms, and the three rod coupler geometry. Both analytical and experimental investigations were made of the coupler's operation. (Author)
