The purpose of this study is to present a security system that combines PDM and SDM and is based on the flexible configuration of multi-channel keys. The proposed system will utilize three distinct…
Training supervised video captioning model requires coupled video-caption pairs. However, for many targeted languages, sufficient paired data are not available. To this end, we introduce the unpair…
Influence maximization is a crucial issue for mining the deep information of social networks, which aims to select a seed set from the network to maximize the number of influenced nodes. To evaluat…
Reduced coating diameter fibers (RCDF) are attractive for increasing fiber density in cables due to their compatibility with the standard 125 μm clad diameter. In this paper, we review recent prog…
Orbital angular momentum (OAM) mode multiplexing provides a promising solution for enlarging communication capacity density. Although various OAM mode multiplexing technologies have been investigat…
We demonstrate a widely tunable narrow linewidth dual-wavelength Yb-doped fiber laser with switchable inhomogeneous polarization output based on the Pancharatnam-Berry phase optical elements and vo…
An approach to generating periodic spiking and spiking cluster in a broadband nonlinear opto-electronic oscillator (OEO) is proposed and demonstrated. Through injecting a long-duration square-wave …
Polarization devices on lithium niobate thin film (LNTF) are vital components for photonic integrated circuits (PICs) on the novel platform. Because both linear and nonlinear devices on the anisotr…
In this paper, an encrypted three-dimensional (3D) trellis-coded modulation (TCM) based on mapping by set-partitioning (MSP) of 3D constellation is proposed, for highly reliable and secure short-re…
We experimentally demonstrate a Brillouin fiber laser (BFL) with a low threshold and narrow linewidth at 2 μ m employing a chalcogenide As 2 S 3 fiber as the Brillouin gain fiber. The As 2 S 3 fib…
