Fast Autofocusing Algorithm Based on Variable Step Search and Curve Fitting A…
We design a set of near- and far-field detection system with a common optical path. And we propose a fast autofocusing algorithm based on variable step search and curve fitting for defocus aberrati…
Ultra-Wideband OAM Mode Generator Based on a Helical Grating Written in a Gra…
An ultra-wideband orbital-angular-momentum (OAM) mode generator has been proposed and demonstrated both theoretically and experimentally, which is based on a helical long period fiber grating (HLPG…
Cascade Uni-Traveling-Carrier Photodetector Array for Terahertz Applications
A cascade array structure and depleted layer thickness design method of uni-traveling-carrier photodetector (UTC-PD) for terahertz applications is proposed. The cascade array structure can increase…
Pyramidal Semantic Correspondence Networks
This paper presents a deep architecture, called pyramidal semantic correspondence networks (PSCNet), that estimates locally-varying affine transformation fields across semantically similar images. …
Real-Time FPGA Investigation of Potential FEC Schemes for 800G-ZR/ZR+ Forward…
Forward error correction (FEC) performance down to 1e-15 bit error rate (BER) of a open FEC code (OFEC), which was recently proposed for the 800G inter-data center interconnect (DCI) standard, is v…
A Microwave Photonic Channelized Receiver With Self-Interference Cancellation
Microwave photonic channelized receiver can break through the electronic bottleneck, improve the throughput of satellite payload, and is expected to be widely used in broadband satellite communicat…
Wavelength Modulated Anti-Resonant Fiber-Optic Microfluidic Device Based on S…
A wavelength modulated microfluidic device based on hollow core tube fiber (HCTF) is proposed, the modal dispersion and field distributions of the liquid-filled HCTF are analyzed and simulated base…
Brillouin Optical Correlation Domain Analysis With Over 2.5 Million Resolutio…
We propose and experimentally demonstrate a long-range Brillouin optical correlation domain analysis (BOCDA) system based on distributed Raman amplification and injection-locking to reach over 2.6 …
Parametric Optimization for Low Loss Negative Curvature Hollow Core Fiber Wit…
Negative curvature hollow core fiber (NC-HCF) with elliptical tubes is beneficial for low confinement loss (CL) due to the rich degree of freedom in tube curvature. In this paper, an empirical form…
Deep Learning-Based Channel Modeling for Free Space Optical Communications
Instead of conventional knowledge-driven modeling, this study introduced data-driven channel modeling methods based on deep learning (DL) in a free-space optical (FSO) communication system to achie…
