Experimental Investigation of Mode Diversity Reception Using an Optical Turbulence Generator and Digital Holography
arXiv:2209.06821
Abstract
Mode diversity reception is experimentally investigated using an optical turbulence generator, off-axis digital holography, and digital demultiplexing. The results confirm improved fibre coupling efficiency when receiving the optical field using a multi-mode fibre instead of a single-mode fibre under turbulent conditions, specifically beam wander. The coupling loss is reduced by receiving additional modes.
