Journal ArticleDOI
Intensity-only Mode Decomposition on Multimode Fibers using a Densely Connected Convolutional Network
TL;DR: It is shown for the first time that by using a DenseNet with 121 layers it is possible to break through the hurdle of 6 modes and perform mode decomposition on a subset of 10 modes of a 55-mode fiber, which also supports modes unknown to the neural network.
Journal ArticleDOI
Transmission Matrix Measurement of Multimode Optical Fibers by Mode-Selective Excitation Using One Spatial Light Modulator
TL;DR: In this article, a mode-selective excitation of complex amplitudes is performed with only one phase-only spatial light modulator, and the light field propagating through the fiber is measured holographically and is analyzed by a rapid decomposition method.

TL;DR: This is the first time that physical layer security has been investigated in a fiber optical network based on measured transmission matrices and the results show that messages can be sent securely using traditional communication techniques.
Journal ArticleDOI
Deep Learning for Computational Mode Decomposition in Optical Fibers
TL;DR: In this paper, a deep neural network is used to determine the amplitude and phase information from simple intensity-only camera images, which is similar to digital holography, but requires significantly smaller efforts.
