Abstract
Methods for connecting two optical fibers having different mode field diameters ((MFD) with low connection loss is proposed. One method comprises steps of preparing the third fiber (Fiber ), a short length and MFD being smaller than that of the first fiber (Fiber ) and larger than that of the second (Fiber ), connecting the Fiber to connecting Fiber to and increasing MFD of Fiber near the part connected or to be connected to Fiber or MFD of Fiber near the part connected or to be connected to Fiber by heating the corresponding part. The other method comprises steps of preparing a short length Fiber having smaller MFD than that of Fiber increasing MFD of Fiber near the part to be connected to Fiber by heating the corresponding part, and then connecting Fiber to and to in that order.
