Coupling efficiency of optics in single-mode fiber components
TLDR
This paper combines fiber-coupling fundamentals, classical optics, and diffraction theory to provide a compact description of coupling efficiency that includes the effects of aberrations, fiber misalignments, and fiber-mode mismatch.Abstract:
Many single-mode fiber components include some form of optics, such as lenses or mirrors, for collecting light from a source fiber or laser and concentrating it on a receiving fiber. For such components there is a direct and simple relationship between coupling efficiency and optical aberrations. This paper combines fiber-coupling fundamentals, classical optics, and diffraction theory to provide a compact description of coupling efficiency that includes the effects of aberrations, fiber misalignments, and fiber-mode mismatch.read more

Alignment of Gaussian beams.
W B Joyce,B C DeLoach +1 more
TL;DR: The design of a coupling between a semiconductor laser and a single-mode fiber, or between any two optical or acoustical elements that support Gaussian modes, is presented as a trade-off among coupling efficiency T(a), offset misal alignment tolerance d(e), and angular misalignment tolerance theta(e).

Free-space beam propagation between arbitrarily oriented planes based on full diffraction theory: a fast Fourier transform approach
TL;DR: In this paper, a fast and accurate numerical method for free-space beam propagation between arbitrarily oriented planes is developed, which is based on evaluating the Rayleigh-Sommerfeld diffraction integral by use of the fast Fourier transform with a special transformation to handle tilts and offsets of planes.

Loss analysis of single-mode fiber splices
TL;DR: In this paper, the authors consider the possibility that the two fibers of different dimensions are separated in longitudinal direction and are tilted or offset with respect to each other, and the trade-off between slice tolerances with regard to tilt and offset is expressed as an uncertainty principle.
