摘要

Abstract

Free-space optics naturally offers multiple-channel communications and sensing exploitable in many applications. The different optical beams will

however

generally be overlapping at the receiver

and

especially with atmospheric turbulence or other scattering or aberrations

the arriving beam shapes may not even be known in advance. We show that such beams can be still separated in the optical domain

and simultaneously detected with negligible cross-talk

even if they share the same wavelength and polarization

and even with unknown arriving beam shapes. The kernel of the adaptive multibeam receiver presented in this work is a programmable integrated photonic processor that is coupled to free-space beams through a two-dimensional array of optical antennas. We demonstrate separation of beam pairs arriving from different directions

with overlapping spatial modes in the same direction

and even with mixing between the beams deliberately added in the path. With the circuit's optical bandwidth of more than 40 nm

this approach offers an enabling technology for the evolution of FSO from single-beam to multibeam space-division multiplexed systems in a perturbed environment

which has been a game-changing transition in fiber-optic systems.
