Abstract
The present invention provides a mode field conversion fiber component formed by fusion-connecting connection end surfaces of two optical components having different mode fields. The mode fields of the two optical components are conformed to each other at the connection end surfaces, and are continuously varied near the connection end surfaces. The present invention also provides a method for manufacturing a mode field conversion fiber component, having the steps of butting connection end surfaces of two optical fibers having different mode fields, fusion-connecting the connection end surfaces of the two optical fibers, and heating a fusion-connecting portion of the connection end surfaces, diffusing core dopant, and conforming the mode fields of the two optical fibers.
