We experimentally demonstrated, for, it is believed, the first time, high-capacity polarization-
and mode-division multiplexing free-space optical transmission with adequate strong …

We investigated the performance of mode diversity reception of a polarization-division-
multiplexed (PDM) signal with few-mode-fiber (FMF) coupling for high-speed free-space …

We experimentally demonstrate the enhanced atmospheric turbulence resiliency in a 137.8
Gbit/s/mode mode-division multiplexing free-space optical communication link through the …

We improved the coupling efficiency to the free-space optical receiver by using a few-mode
fiber with the optical signal distorted with a turbulence emulator. We demonstrated digital …

We experimentally demonstrate 10-channel mode-division multiplexed free-space optical
transmission with five spatial modes, each carrying 19.6925-Gbaud dual-polarization …

In general, atmospheric turbulence can degrade the performance of free-space optical
(FSO) communication systems by coupling light from one spatial mode to other modes. In …

We experimentally demonstrate a high-spectral-efficiency, large-capacity, featured free-
space-optical (FSO) transmission system by using low-density, parity-check (LDPC) coded …

We employ commercial mode-selective photonic lanterns to implement mode multiplexing
and demultiplexing for high-capacity free-space optical communications. Moreover, we …

In this paper, we propose a novel pilot-aided phase and channel estimation algorithm for
coherent mode-division multiplexing multiple-input multiple-output free-space optical …

A single multi-plane light convertor (MPLC) is applied to simultaneously mitigate turbulence-
induced crosstalk and demultiplex two orbital angular momentum (OAM) multiplexed …
