Abstract
Fiber/D-fiber splice loss can be minimized by precise axes misalignment. We present an accurate analysis of single-mode fiber/D-fiber splice at the telecommunication wavelengths (lambda) equals 1.3 micrometers and (lambda) equals 1.55 micrometers , by using a combination of vectorial finite element method and mode matching method. Splice loss variation is investigated in terms of fiber axes transverse offset for various D-fiber core-to-flat distances, and the optimum offset that minimizes splice loss is determined. The effect of fiber-axes rotation is also investigated for non null offsets. Fiber axes positioning tolerances are also evaluated for a given percentual loss variation.
