Identifying surgical phases is a crucial component of surgical workflow analysis, facilitating the automated evaluation of surgical procedures’ performance and efficiency. A significant challenge in developing neural networks for surgical phase...

This paper addresses the challenge of real-time rendering of dynamic 3D scenes using Instant Neural Graphics Primitives (iNGP), training a separate radiance field for each frame. To enable interactive VR playback, efficient data storage and...

Spatial-diversity schemes are applied to improve signal quality of coherent free-space optical transmission systems with uncorrelated phase noise. We compare the performance of conventional schemes (MRC, SDC) to a newly proposed one (X-MRC).

Researchers from the University of L’Aquila, NICT, Finisar, Prysmian, Nokia Bell Lab and Fraunhofer HHI Space-Division Multiplexed Transmission technologies from the Lab to the Field and present a summary for their work in this invited...

Single-photon avalanche detectors (SPADs), which operate without cryogenic cooling, are a core component for practical QKD systems. We demonstrate 13-hour continuous key generation with our timebin-phase BB84 QKD system using our InGaAs/InP SPAD,...

To enable QKD in various scenarios, we developed a 625 MHz real-time autonomous timebin-phase QKD system with custom clock synchronization. We demonstrate the system’s performance and robustness under unstable link conditions, a variety of fiber...

We investigate high-symbol rate SDM transmission using 16 to 128 GBd QPSK, 16-QAM and 64-QAM modulation over a 3-mode fiber. An aggregated net rate of 2.56 Tb/s was obtained after 54 km transmission using 128 GBd 16-QAM signals.

We introduce iQSync, a clock-offset recovery method for quantum key distribution. iQSync achieves sub-linear computational complexity, allowing for the implementation on low-level hardware. We demonstrate the method for channel attenuations...

A narrow linewidth tunable laser based on ring resonators is presented. It uses low loss passive waveguides implemented in a monolithic InP photonic integrated circuit. The laser can be tuned over a wavelength range from 1559 nm to 1602 nm. The...

3D Gaussian Splatting (3DGS) is a powerful technique for real-time radiance field rendering but is limited by its high storage and memory requirements. This survey provides the first comprehensive analysis of existing compression and compaction...
