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…
Structured Beamforming Based on Orbital Angular Momentum Mode-Group
The structured beams, which can manipulate arbitrary intensity and phase of electromagnetic rays, are significant in communication and sensing. The vortex electromagnetic wave carrying orbital angu…
A New Perfectly Matched Layer Method for the Helmholtz Equation in Nonconvex …
A new coupled perfectly matched layer (PML) method is proposed for the Helmholtz equation in the whole space with inhomogeneity concentrated on a nonconvex domain. Rigorous analysis is presented fo…
Unsupervised Intrinsic Image Decomposition Using Internal Self-Similarity Cues
Recent learning-based intrinsic image decomposition methods have achieved remarkable progress. However, they usually require massive ground truth intrinsic images for supervised learning, which lim…
Adaptive Action Assessment
Action assessment, the process of evaluating how well an action is performed, is an important task in human action analysis. Action assessment has experienced considerable development based on visu…
Cascaded Feedforward Neural Network Based Simultaneously Fast and Precise Mul…
We present and investigate a scheme to realize fast and precise multi-characteristics extraction and error estimation of Brillouin frequency shift (BFS) simultaneously based on a cascaded feedforwa…
Ultra-Widely Tunable Acousto-Optic Add-Drop Filter Based on Acoustically-Indu…
An ultra-widely tunable acousto-optic add-drop filter is proposed and demonstrated based on the acoustically-induced polarization conversion of cladding-etched single-mode fiber, which covers wavel…
Optical Spectral Shaping Based on Reconfigurable Integrated Microring Resonat…
We demonstrate a multifunctional optical spectral shaper on a silicon photonic chip. The proposed structure is composed of a tunable microring resonator (MRR) and three tunable Sagnac loop mirrors …
Evaluation of Optical Transport Unit Line-Card Integration in Spatially and S…
The explosive growth of internet traffic has accelerated the evolution of optical transport networks, emphasizing the need to expand transmission capacity. To overcome the limitations of convention…
Physics-Based Noise Modeling for Extreme Low-Light Photography
Enhancing the visibility in extreme low-light environments is a challenging task. Under nearly lightless condition, existing image denoising methods could easily break down due to significantly low…
