Real-Time Definite Sequence Modulation Based Spectral Broadening Scheme for H…
High-power narrow-linewidth continuous fiber lasers have wide applications in the fields of power synthesis, nonlinear frequency conversion, and industrial processing. The output power of kW or eve…
Sawtooth Fiber MZ Vector Bending Sensor Available for Multi Parameter Measure…
In this paper, a fiber Mach Zehnder (MZ) interferometer based on sawtooth structure was proposed. It not only has the ability of bending sensing and bending direction recognition, but also can be a…
2.3 W, Linearly-Polarized Superfluorescent Generation From a Polarization-Mai…
We present a high-power, polarization-maintaining (PM) Er 3+ -doped fluoride fiber amplifier, which enables watt- level, linearly-polarized (LP) superfluorescent outputs around 2.8 μm by using a n…
Seek-and-Hide : Adversarial Steganography via Deep Reinforcement Learning
The goal of image steganography is to hide a full-sized image, termed secret, into another, termed cover. Prior image steganography algorithms can conceal only one secret within one cover. In this …
Learning Human Activity Patterns Using Clustered Point Processes With Active …
Modeling event patterns is a central task in a wide range of disciplines. In applications such as studying human activity patterns, events often arrive clustered with sporadic and long periods of i…
Dual Concentric-Ring-Core Fiber With Four Zero-Dispersion Wavelengths for Bey…
Orbital angular momentum (OAM) beams, featuring with unique spatial field distributions, have been extensively investigated and applied into a wide range of fields. In most applications, OAM beams …
Highly Dispersive Optical Fiber for Orbital Angular Momentum Modes
Orbital angular momentum (OAM) modes, featured by the unique properties of the helical phase front and annular intensity profile, have shown enormous potential for a wide range of applications. Opt…
Switchable Dual-Band Binary and Single-Band Quaternary Phase-Coded Microwave …
A switchable dual-band binary and single-band quaternary phase-coded microwave signal generator based on a single dual-polarization dual-drive Mach–Zehnder modulator (DP-DDMZM) is proposed. Two r…
High-Resolution Optical Fiber Strain Sensor Array Based on Pound-Drever-Hall …
Sensors that use Pound-Drever-Hall (PDH) technology benefit from the good performance and high resolution but are in shortage of large-scale multiplexing. This paper proposed a fast phase regulatio…
Flat-Top Soliton Frequency Comb Generation Through Intra-Cavity Dispersion En…
Dissipative Kerr cavity soliton and optical frequency comb (OFC) can be generated in fiber cavities or microresonators with anomalous group velocity dispersion (GVD), which has achieved great break…
