With free space optical (FSO) communication systems, information is generally transmitted to minimize diffraction. Here, we demonstrate an alternate paradigm, "diffractal space-division multiplexing" (DSDM), in which the diffraction of fractals enable a wider cone for reception to support roaming transceiver. As a result, DSDM is robust to misalignment over longer-distance links. We examine the consequence of mid-field, non-far-field propagation and the result on kernel bit error rates. The sparse and redundant encoding of information in DSDM may be relevant to other FSO acquisition, pointing, and tracking.

For free space optical (FSO) communication, a small misalignment of the transceivers may result in link failure or severe performance degradation. It can be difficult to track the narrow optical beams over long distances. Here, we propose “diffractal space-division multiplexing” (DSDM), an FSO transmission system capable of supporting misaligned roaming transceivers. This system enables spatial multiplexing for enhanced data capacity with partial off-axis beam reception. We numerically simulate and analyze the performance of the DSDM system with a particular focus on the divergence angle, roaming area, kernel bit-error-rate (K-BER), and fractal order. Our simulation results achieve K-BERs of 10$$^{-3}$$ - 3 with $$81\times 81$$ 81 × 81 -pixel fractal beams at link distances of 2.5 km when the receiver sizes are 30$$\%$$ % of the effective beam diameter.
