Title: Advancing multicore fiber endoscopy and multimode fiber communication using deep learning and modern holography
Abstract: Optical fibers play a crucial role for important applications in biomedicine and communication. Light has the potential to recognize the development of diseases, to prevent them or to heal them early and gently. Multicore fiber endoscopy is crucial for several diagnostics. Traditionally, however, lens-based imaging results in bulky systems. We will outline the 3D imaging with needle-sized endoscopes. Lensless fiber endoscopy exploiting deep learning and modern holography shows promise for novel cancer diagnostics in neurosurgery. Multimode fibers show promise for improving data rates in optical communications, but come with the challenge of compensating for modal crosstalk. By measuring the transmission matrix, it is not only possible to correct distortions, but also to exploit these effects to establish a confidential data connection between legitimate communication partners. Physics-informed deep neural networks and modern digital holography are involved. The proposed real-time transmission matrix measurements enable physical layer security and quantum communications. The memory effect of multicore fibers and the mode dependent losses of multimode fibers are highlighted for advances in needle-thin 3D endoscopes and for secure data communication, respectively.
