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…
Theoretical Analysis of the Mode Distortion Induced by Stimulated Raman Scatt…
By employing the mode decomposition method to study the relative mode evolution characteristics during the stimulated Raman scattering (SRS) process, a numerical model of the core-pumped Raman effe…
Receiver IQ Imbalance and Skew Compensation for High Order Modulation Formats…
A typical coherent front-end may encounter imperfections, such as amplitude imbalance, phase imbalance and skew, between four sampling channels. These receiver (Rx) imperfections, together with tra…
A Polarization-Insensitive High-Resolution Micro-Spectrometer Using (N + 3) Ã…
Ultra-compact on-chip spectrometers with high resolution and large bandwidth play a crucial role in miniaturized spectroscopic analysis systems. Here we present a novel polarization-insensitive mic…
Modulation Format Identification Technology Based on a Searching Cluster Boun…
In this study, a modulation format identification (MFI) scheme based on a searching cluster boundary (SCB) algorithm is designed for space optical communication. Particularly, we design a clusterin…
The Generation of 1.2 μJ Pulses From a Mamyshev Oscillator Based on a High C…
We demonstrate a high-energy and high-average power Mamyshev oscillator based on a high performance large-mode-area step-index germanosilicate-cladding Yb-doped fiber. The oscillation of higher-ord…
Photonic Generation of a Windowed Phase-Coded Microwave Waveform With Suppres…
An approach to photonic generation of a windowed binary phase-coded microwave waveform with suppressed spectrum sidelobes is proposed and demonstrated. An optical double sideband plus carrier signa…
University Blockchain Research Initiative (UBRI): Boosting Blockchain Educati…
Since its conceptualization, blockchain technology has witnessed continuous and rapid development, bringing profound changes to computer science, law, and economics. In 2008, the initial blockchain…
High Speed and High Sensitivity InGaAs/InAlAs Single Photon Avalanche Diodes …
A planar InGaAs/InAlAs single photon avalanche diode (SPAD) was fabricated and comprehensively characterized. At room temperature, the dark count rate is 3.1 MHz at 10.4% photon detection efficienc…
Design and Performance Test of Pulse X-Ray Receiver Based on LYSO-SiPM for X-…
X-ray communication (XCOM) is a type of wireless optical communication technology that uses modulated X-ray beam as the carrier of data transmission. As a core component of an XCOM system, the X-ra…
