Tapping Eavesdropper Designs Against Physical Layer Secret Key in Point-to-Po…

With the growing demand for service access and data transmission, security issues in optical fiber systems have become increasingly important and the subject of increased research. Physical layer s…

Revisiting the Stress-Induced Birefringence in Polarization-Maintaining Fibers

Two conventional errors in the stress-induced birefringence (SIB) of polarization-maintaining fibers (PMFs) are revealed and corrected. The first issue refers to the fundamental expression and its …

Intra-Channel Nonlinearity Mitigation in Optical Fiber Transmission Systems U…

In this work, a perturbation-based neural network (P-NN) scheme with an embedded bidirectional long short-term memory (biLSTM) layer is investigated to compensate for the Kerr fiber nonlinearity in…

High-Dimensional Feature Based Non-Coherent Detection for Multi-Intensity Mod…

Ultraviolet communication (UVC) has been regarded as a promising supplement for overloaded conventional wireless communications. One challenge lies in the communication deterioration caused by the …

Nonlinear Coherent Optical Systems in the Presence of Equalization enhanced P…

Ultrasensitive Label-Free Biosensor Based on the Graphene-Oxide-Coated-U-Bent…

In this article, we theoretically and experimentally report a newly-designed biosensor, which consists of a particular graphene-oxide (GO)-coated-U-bent long-period fiber grating inscribed in a two…

High Accuracy and Real-Time Positioning Using MODWT for Long Range Asymmetric…

The key technology to demodulate the vibration position along the sensing fiber link in the asymmetric fiber interferometer based vibration sensors is to extract similar variation features with hig…

Non-Coherent Detection for Ultraviolet Communications With Inter-Symbol Inter…

Ultraviolet communication (UVC) serves as a promising supplement to share the responsibility for the overloads in conventional wireless communication systems. One difficulty lies in how to address …
