Multimode Optical Fiber Transmission With A Deep Learning Network

Deep learning networks have been employed earlier for imaging through multimode fibers but the large amount of data required for training the network was an obstacle.

Multimode optical fiber transmission with a deep learning network. Multi mode fiber is mainly used to transmit across comparatively shorter distances as the modes are more likely to disperse over longer extents. Science applications 7 1 december 2018 with 213 reads how we measure reads. Multimode fibers mmf are an example of a highly scattering medium which scramble the coherent light propagating within them and produce seemingly random patterns. Multimode fibers mmfs are an example of a highly scattering medium which scramble the coherent light propagating within them to produce seemingly random patterns.

Multi mode fiber is a type of optical fiber designed to carry multiple light rays or modes simultaneously each at a marginally different reflection angle inside the optical fiber core. The network was trained with experimental data to learn the relation between the input spatial beam profile of the pump pulse and the spectrum of the light at the output of the multimode fiber. Thus for applications such as imaging and image projection through a mmf careful measurements of the relationship between inputs and outputs of the fiber are required. We show as a proof of concept that a deep neural.
