Abstract :
Fiber/D-fiber splice loss can be minimized by precise axial offsetting. We present an accurate loss analysis of single-mode fiber/D-fiber splice by using a combination of vectorial finite-element method and mode matching method. The splice between fiber and D-fiber with same or different refractive index difference is considered. Splice loss variation is investigated in terms of transverse offset between fiber axes and axial rotation, for various values of the D-fiber core-to-flat distance. It is found that optimum values of offset and rotation exist that minimize splice loss for a given D-fiber core-to-flat distance.<>
