When multimode optical fibers are perturbed, the data that is transmitted through them is scrambled. This presents a major difficulty for many possible applications, such as multimode fiber based telecommunication and endoscopy. To overcome this challenge, a deep learning approach that generalizes over mechanical perturbations is presented. Using this approach, successful reconstruction of the input...
In the past ten years, many techniques were developed to control light propagation in complex transmission media using spatial light modulators. It involved applications in numerous fields [1–2] including biomedical imaging and therapy, fiber endoscopy, cryptography, optical micromanipulation, optical spectroscopy, telecommunications and random lasers and also served as a tool for fundamental studies...
We study numerically the effects of optical absorption on highly transmitting channels in strongly scattering media. We observe that they are robust against weak absorption. Surprisingly, in case of strong absorption diffusive transport becomes ballistic-like.
We investigate experimentally two counter-propagating beams that travel through multimode fibers with strong mode coupling. The interferences between waves going through time-reversed paths can enhance, and surprisingly sometimes suppress, coherent backscattering to the input mode.
We experimentally demonstrate an encryption method for transmission through multimode fibers. The encryption is provided by chaotic mode mixing, and time-reversal symmetry of counter-propagating light ensures that only an authorized party can decrypt the message.
