Multilayer Optical Learning Networks [PDF]
In this paper we present a new approach to multilayer neural network learning which is based on holographically interconnected nonlinear Fabry-Perot etalons. The network can learn the interconnections that form a distributed representation of a desired pattern transformation operation.

Generation of the First-Order OAM Modes in Ring Fibers by Exerting Pressure Technology
We have proposed an effective method of generating the first-order orbital angular momentum (OAM) modes in ring fibers. The first-order OAM modes (${\rm{L = \pm 1}}$ ) can be represented as the linear superposition of the ${\rm{HE}}_{{21}}^{{\rm{even}}}$
