Delivery of Polarization-Division-Multiplexing Wireless Millimeter-Wave Signa…

We proposed and established a large-capacity, long-distance wireless millimeter-wave (mm-wave) signal delivery system at W-band based on photonics-aided mm-wave generation technology, polarization-…

Angle-Spliced SMF to Hollow Core Fiber Connection with Optimized Back-Reflect…

We study and demonstrate angle-cleaved fusion splicing between single mode fiber (SMF) and nested anti-resonant node-less fiber (NANF). First, we analyze the trade-off between the connection loss a…

Optical Beams Switching-Based Coverage Enhancement Scheme for Compact Visible…

Visible light communication (VLC) has been recognized as one promising candidate to satisfy the unprecedented throughput requirement of near-future mobile wireless networks. Due to the directional …

Revisiting Spectral Bundle Methods: Primal-Dual (Sub)linear Convergence Rates

The spectral bundle method proposed by Helmberg and Rendl [SIAM J. Optim., 10 (2000), pp. 673–696] is well established for solving large-scale semidefinite programs (SDPs) thanks to its low per i…

AGO-Net : Association-Guided 3D Point Cloud Object Detection Network

The human brain can effortlessly recognize and localize objects, whereas current 3D object detection methods based on LiDAR point clouds still report inferior performance for detecting occluded and…

Object Detection in Aerial Images : A Large-Scale Benchmark and Challenges

In he past decade, object detection has achieved significant progress in natural images but not in aerial images, due to the massive variations in the scale and orientation of objects caused by the…

Orbital Angular Momentum Data Transmission Using a Silicon Photonic Mode Mult…

We designed and fabricated a silicon photonic orbital angular momentum (OAM) multiplexer (MUX) chip that enables simultaneous wavelength-division multiplexing (WDM) and OAM mode-division multiplexi…

Broadband Ultrasound Detection Using Silicon Micro-Ring Resonators

High sensitivity, broadband bandwidth, small size and scalability to a fine-pitch matrix of ultrasound (US) sensors are essential for high-resolution ultrasonography and photoacoustic tomography. I…
