We propose an optical watermarking strategy based on precise bias tuning of an electro-optical modulator and a convolutional neural network-enabled decoder. This scheme can be used for identity aut…
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…
Alibaba, which operates one of the world’s largest e-commerce platforms, designed a comprehensive omnichannel retail infrastructure that enables both online and offline ordering of products, rang…
Multipath interference (MPI) noise suppression is crucial for high-speed 4-level pulse amplitude modulation (PAM4) intensity modulation direct detection (IMDD) transmission systems. In this paper, …
Temporal multiplexed fiber Bragg grating (FBG) sensing system for detecting physical parameters with a high spatial resolution is desirable for applications such as structure health monitoring, oil…
We propose and demonstrate a novelsingle-frequency erbium-doped random distributed Bragg reflector fiber laser (RDBR-FL) constructed by a random fiber grating (RFG) and a high-reflection fiber Brag…
In this paper, we proposed an improved mobile fronthaul architecture employing the SNR-improved delta-sigma digitization scheme and 4-level pulse amplitude modulation (PAM-4) format. Different from…
We propose a temperature sensor, which consists of a composite optical waveguide (COW) sandwiched between two single mode fibers (SMFs). The COW is formed by side polishing a capillary optical fibe…
We propose and demonstrate the power scalability in a novel random Raman fiber laser (RRFL) with localized random feedback provided by an ultrashort low-reflection random fiber grating (RFG). The R…
A taper-based in-line Mach-Zehnder interferometer (MZI) coated with the magnetic fluids (MFs) is designed and experimentally verified for the highly sensitive magnetic field measurement. The effect…
