摘要：

A spotsize reducer for single-mode fibers (SMF's) was fabricated by use of the quarter-pitch length of a parabolic-index fiber tip having a high focusing parameter. The modal-field diameter of a standard SMF at a wavelength of 1.55 mu m has been reduced from 10.4 to 5.8 mu m, with the use of the tip. The reducer appears promising for low-loss coupling between standard SMF's and various waveguides, such as dispersion compensated fibers, erbium-doped fibers, and planar waveguides.
