3D photonic integrated interposer enabling connectivity between multicore fibers and photonic integrated circuits
A novel 3D photonic integrated interposer is developed for coupling the different layers of Multi-core-fiber (MCF) cores with arrays of conventional 2D electro-absorption modulated lasers (EMLs) and photodetectors (PDs). The 3D photonic...
Next Generation XR Systems-Large Language Models Meet Augmented and Virtual Reality
Extended Reality (XR) is evolving rapidly, offering new paradigms for humancomputer interaction. This position paper argues that integrating Large Language Models (LLMs) with XR systems represents a fundamental shift toward more intelligent,...
3D-Printed Dual-Polarized Magneto-Electric Dipole Antenna with Wideband High Isolation for Full-Duplex Applications
This paper presents a dual-polarized magneto-electric dipole antenna with orthogonal Gamma and inverted-Gamma probes, fabricated via 3D metal printing. It offers a 3-4 GHz impedance bandwidth, with excellent cross-polarization isolation (>50...
Adaptive and Temporally Consistent Gaussian Surfels for Multi- view Dynamic Reconstruction
We propose AT-GS, a novel method for reconstructing high-quality dynamic surfaces from multi-view videos through per-frame incremental optimization. To avoid local minima across frames, we introduce a unified and adaptive gradient-aware...
Automatic Drywall Analysis for Progress Tracking and Quality Control in Construction
This paper presents an automated drywall analysis method for construction progress and quality assessment using on-site cameras. It integrates a deep learning-based segmentation model to detect and classify drywall elements, with a module to...
Improving Geometric Consistency for 360-Degree Neural Radiance Fields in Indoor Scenarios
NeRFs struggle with low-textured areas, causing "floaters" that reduce realism, especially on featureless surfaces. We propose a method for computing dense depth priors for these areas, using a novel depth loss function and patch regularization...
Experimental Demonstration of a Correlation-Avoidance CMA for Blind Space-Division Multiplexed MIMO Equalization
We demonstrate blind 6x6 adaptive equalization of 32 GBd DP-QPSK 3-mode transmission over a 54 km FMF based on the singularity-free convergence ability of the correlation-avoidance CMA (CA-CMA). The CA-CMA is used for robust pre-convergence in a...
7.75 Gbit/s LiFi Transmitter Using High-Power VCSEL Arrays
We report on a wide-beam LiFi transmitter using multiple VCSEL arrays with digital drivers. We transmit a 3.75 GBd PAM-3 signal at a gross data rate of 5.625 Gbit/s. Single-driver OOK operation yields 7.75 GBd.
Data Governance Framework for Telemetry Sharing
We propose a novel solution using the Eclipse Dataspace Components (EDC) Connector to enable regulated and policy-driven telemetry data sharing in telco ecosystems. We present its architecture, several compatible use-cases, and results validating...
Link Tomography: A Tool for Monitoring Optical Network and Designing Digital Twins
Researchers from Deutsche Telekom AG and Fraunhofer HHI explores the Link Tomography, a receiver-based DSP approach for monitoring optical networks and detecting anomalies. Delving into concepts and building methodologies, it addresses challenges...
