Design of a Mach-Zehnder Interferometric Fiber Sensing System Based on PCA-As…
We propose and numerically design a Mach-Zehnder interferometric sensing system using principal-component-analysis-based orbital angular momentum (OAM) interrogation for simultaneous measurement of…
ABCNet v2 : Adaptive Bezier-Curve Network for Real-Time End-to-End Text Spotting
End-to-end text-spotting, which aims to integrate detection and recognition in a unified framework, has attracted increasing attention due to its simplicity of the two complimentary tasks. It remai…
Singularity Reconfiguration of Non-Diffraction Structured Light
It's a basic characteristic that there exists a phase singularity located at the center for pure vortex light. If combining several vortex lights belonging to the same eigenmode set, the central hi…
Bridging the Gap Between Few-Shot and Many-Shot Learning via Distribution Cal…
A major gap between few-shot and many-shot learning is the data distribution empirically oserved by the model during training. In few-shot learning, the learned model can easily become over-fitted …
Structured Multimodal Attentions for TextVQA
Text based Visual Question Answering (TextVQA) is a recently raised challenge requiring models to read text in images and answer natural language questions by jointly reasoning over the question, t…
Transferable Coupled Network for Zero-Shot Sketch-Based Image Retrieval
Zero-Shot Sketch-Based Image Retrieval (ZS-SBIR) aims at searching corresponding natural images with the given free-hand sketches, under the more realistic and challenging scenario of Zero-Shot Lea…
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…
Phase Off-Axis Modulation Metasurface for Orbital Angular Momentum Mode Multi…
Orbital angular momentum (OAM) mode multiplexing provides a promising solution for enlarging communication capacity density. Although various OAM mode multiplexing technologies have been investigat…
Waving Effect Characterization for Water-to-Air Optical Wireless Communication
In this paper, we establish and experimentally verify a water-to-air (W2A) visible light communication (VLC) system through dynamic air-water interface. Considering the complexity of waves in real …
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…
