Research on 3D Optical Module Integrating Edge Coupler and TSV
3D integration photonic interposer is becoming popular in the field of co-packaging optics (CPO). In this paper, we integrate the edge coupler and through silicon via (TSV) into the silicon interpo…
Bi-Directional Self-Homodyne Transmission With MIMO-Free DSP for Next-Generat…
We propose and demonstrate bi-directional (BiDi) self-homodyne coherent detection (SHCD) system experimentally, in which the multiple input multiple output free (MIMO-free) digital signal processin…
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…
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…
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…
Physics-Informed Neural Network for Optical Fiber Parameter Estimation From t…
For any system that follows rigorous mathematical and physical theories like fiber-optic system, system parameter estimation is crucial for system detection and monitoring. In this paper, a physics…
Ultra-High Sensitive Fiber Optic Hydrogen Sensor in Air
A compact fiber optic hydrogen sensing system employing self-referenced configuration and controllable light heating technologies, is proposed and experimentally demonstrated with ultra-high sensit…
Evolutionary Sequential Transfer Optimization for Objective-Heterogeneous Pro…
Evolutionary sequential transfer optimization is a paradigm that leverages search experience from solved source optimization tasks to accelerate the evolutionary search of a target task. Even thoug…
Applications of Physics-Informed Neural Network for Optical Fiber Communications
Due to the capability of the physics-informed neural network (PINN) to solve complex partial differential equations automatically, it has revolutionized the field of scientific computing. This arti…
Rejoinder : Heterogeneous Impact of Brands’ Support for Black Lives Matter …
We discuss three main lines of comments on our paper: internal validity of the research given consumers’ potential misunderstanding of Black Lives Matter (BLM), challenges to the causal inference…
