Overlap relation between free-space Laguerre Gaussian modes and step-index fiber modes.

The definitive version is published in the Journal of the Optical Society of America A, vol.32(9), pp 1678-1682.We investigated the overlap relation of the free-space Laguerre–Gaussian modes to the corresponding linearly polarized modes of a step-index fiber. To maximize the overlap for an efficient coupling of the free-space modes into a fiber, the scale-dependent overlap was theoretically and experimentally determined. The presented studies pave the way for further improvement of free-space to fiber optical connections.enLaser beam characterizationComputer holographyFiber opticsArticleBruning, R., Zhang, Y., McLaren, M., Duparre, M., & Forbes, A.
