Reflective-Type High Sensitivity Optical Fiber Hydrogen Sensor Based On Enlar…
Highly sensitive reflective-type fiber hydrogen sensor based on an enlarged taper cascaded with a tilted fiber grating (TFBG) was proposed. Hydrogen-sensitive Au-Pd nanofilm was coated on the TFBG …
7-M/130-Mbps LED-to-LED Underwater Wireless Optical Communication Based on Ar…
In this paper, the arrays consist of series-connected monochromatic light-emitting diodes (LEDs) are proposed as the transmitter and receiver to implement an LED-to-LED underwater wireless optical …
A Novel Millimeter Wave Receiver Enhanced by a Metallic Dipole Antenna and an…
The ever-demanding requirement for higher data transmission rate has pushed the carrier frequency in wireless communications from centimeter to millimeter waves (MMW) or even terahertz band. Hybrid…
Locating and Counting Heads in Crowds With a Depth Prior
To simultaneously estimate the number of heads and locate heads with bounding boxes, we resort to detection-based crowd counting by leveraging RGB-D data and design a dual-path guided detection net…
A ‘DOMZM–Filter–BPD’-Based Microwave Photonic Link for Eliminating Ev…
The ‘Mach-Zehnder modulator (MZM)–wavelength division demultiplexer (WDM)–photodetector (PD)’ structure in photonic analog-to-digital converters (PADCs) may result in residual even harmonic…
Lithium Niobate Thin Film Polarization Beam Splitter Based on Asymmetric Dire…
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…
Modulation Bandwidth Enhancement and Frequency Chirp Suppression in Two-Secti…
We demonstrate a two-section distributed feedback (DFB) laser for direct modulation based on the reconstruction equivalent chirp (REC) technology. The two-section DFB laser exhibits a stable single…
Side-Coupled Fabry-Perot Resonator Filter Based on Dual-Waveguide Bragg Grating
We propose, analyze and demonstrate a side-coupled Fabry-Perot (F-P) resonator filter composed of two dissimilar waveguides with π phase-shifted Bragg grating. The resonance circuit is formed by t…
Age of Information for the Cellular Internet of Things : Challenges, Key Tech…
With the rapid development of cellular Internet of Things (CIoT), more and more real-time applications appear in our lives, which require timely status updates. To exactly characterize the informat…
Automating Optical Network Fault Management with Machine Learning
Effective fault management is essential for quality of service assurance in optical networks. Conventional fault management designs for optical networks mainly rely on threshold-based rules, which …
