Multi‐mode fibers (MMFs) support high‐capacity optical transmission, making them ideal carriers for remote imaging and high‐throughput optical communication. However, the variable transmission channels of MMF pose major challenges for long‐distance, high‐precision spatial information delivery. Existing static model...

The advent of neural network (NN)-based autoencoders has enabled joint transceiver optimization via end-to-end (E2E) learning. However, most existing approaches rely on differentiable surrogate channel models, leading to performance mismatch when deployed over real-world channels. Emerging model-free variants alleviate...

We demonstrate an underwater visible light communication system using a circularly polarized 520 nm laser transmitter, 32APSK modulation, and a polarization-diverse dual-aperture receiver. An end-to-end post-equalization network, DirectDemodNet, directly maps dual-polarization received waveforms to 32APSK symbol logits...
