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 confirm the potential of receiver-side modal diversity for the mitigation of impairments
induced by atmospheric turbulence in free-space optical communications. On this basis, we …

We propose and demonstrate turbulence-resistant free-space optical communication using
a 10-mode pre-amplified receiver. A 6-dB improvement over a single-mode preamplified …

We report investigations on the mode diversity receiver applied in optical links from low-
earth-orbital satellites to a ground terminal. We numerically simulated temporal power …

In free-space optical communication links, atmospheric turbulence causes fluctuations in
both the intensity and the phase of the received light signal, impairing link performance. We …

We experimentally evaluated performance of a mode diversity receiver in severe fading
channels of emulated LEO-to-ground link. Digital combining of three modes using adaptive …

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 …
