We were able to demonstrate this result for fibers up to 1 km long by training the dnns with a database of 16 000 handwritten digits.
Multimode optical fiber transmission with a deep learning network.
Multimode fibers mmfs are an example of a highly scattering medium which scramble the coherent light propagating within them to produce seemingly random patterns.
We show as a proof of concept that a deep learning neural.
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.
The researchers used the experimentally measured transmission matrix of the multimode fiber to calculate two photon patterns for the purpose of training the network.
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.
We experimentally show that the spectrum of the light at the output of the fiber can be tailored by a trained deep neural network.

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.

Deep neural networks dnns are used to classify and reconstruct the input images from the intensity of the speckle patterns that result after the inputs are propagated through multimode fiber mmf.
Multimode fibers mmf are an example of a highly scattering medium which scramble the coherent light propagating within them and produce seemingly random patterns.
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.
Multi mode fiber is mainly used to transmit across comparatively shorter distances as the modes are more likely to disperse over longer extents.
