Experimental comparison of 3-mode and single-mode coupling over a 1.6-km free-space link

Autor: Curt Schieler, G. Lund, N. K. Fontaine, Bryan S. Robinson, Timothy M. Yarnall, Michael L. Stevens, David J. Geisler, Scott A. Hamilton

Publikováno v: Free-Space Laser Communication and Atmospheric Propagation XXX.

Free-space optical communications links have the perpetual challenge of coupling light from free-space to a detector or fiber for subsequent detection. It is especially challenging to couple light from free-space into single-mode fiber (SMF) in the p
