OAM-SDM Solution Toward a Submarine Cable
Determining how to add more signal channels without enlarging the cable volume is continually an issue in managing submarine cables. To improve the cost per bit and the power efficiency, space divi…
Transportation Origin-Destination Demand Estimation with Quasi-Sparsity
Origin-destination (OD) demands for a city or a region are essential input to many transportation applications. For a real-world transportation network, the OD demand matrix may present certain qua…
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…
Exploring the Balance Between Computational Thinking and Learning Motivation …
Computational thinking (CT) skills are generally regarded as a basic ability for problem-solving and are gradually filtering down to younger age groups. Existing research has attempted to increase …
PRIN/SPRIN: On Extracting Point-Wise Rotation Invariant Features
Point cloud analysis without pose priors is very challenging in real applications, as the orientations of point clouds are often unknown. In this paper, we propose a brand new point-set learning fr…
Distilled Siamese Networks for Visual Tracking
In recent years, Siamese network based trackers have significantly advanced the state-of-the-art in real-time tracking. Despite their success, Siamese trackers tend to suffer from high memory costs…
Fully Integrated Solid-State LiDAR Transmitter on a Multi-Layer Silicon-Nitri…
We report a LiDAR transmitter incorporating both a hybrid-integrated tunable external cavity laser and a high-resolution 2-D optical phased array beam-steerer. Widely tunable single-mode lasing ove…
A High Performance Silicon Nitride Optical Delay Line With Good Expansibility
In this paper, based on the double strip silicon nitride platform, we designed and fabricated a low loss continuously tunable broadband optical delay line, which contains a 5-bit optical switched d…
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…
Broadband 1×8 Optical Beamforming Network Based on Anti-resonant Microring D…
We demonstrate a 1×8 binary tree optical beamforming network (OBFN) chip for a microwave photonic phased array antenna. The OBFN is formed by cascading multiple microring resonators (MRRs) working…
