Abstract: Iso-variance-matrix Laguerre-Gaussian superpositions corresponding to fundamental Laguerre-Gaussian modes are constructed and propagated numerically through atmospheric turbulence. The fact that these superpositions are iso-variance-matrix with the corresponding fundamental Laguerre-Gaussian mode ensures that both the superposition and… read more here.

Abstract: We propose a Hermite-Gaussian (HG) mode-demulti-plexing hybrid (MDH) for coherent detection of mode-division multiplexed signals. The MDH, which performs multiple functionalities, including demultiplexing, local oscillator splitting, and optical 90-deg mixing, is realized based on the… read more here.
