Microwave Photonics Low Phase Noise RF Comb Generator for D- and J-Band
We present a microwave photonic RF comb generator based on a quartz-stabilized, ultra-low phase noise fs-pulse laser in combination with high-speed RF waveguide coupled photodetectors. A generated microwave tone at 270 GHz obtains a low phase...
Can You Do Real-Time Gesture Recognition with 5 Watts?
Accurate and reliable gesture recognition is a central problem in human-computer interaction (HCI). Many applications that make use of gesture recognition call for mobile devices with reduced power consumption, weight and form factors. Recent...
Demonstration of a Si3N4 Microring Resonator-Based Aptasensor for Human Urokinase-type Plasminogen Activator (uPA) Detection in Point-of-Care Diagnostics
We present the first silicon nitride microring aptasensor for detecting the cancer biomarker uP! A on a photonic integrated chip. Combining high optical sensitivity with aptamer-based selectivity, the sensor distinguishes uPA levels and is...
11.5 Gbit/s Transmission Using a 660 mW LiFi Transmitter
For the first time, we demonstrate LiFi transmission with a net data rate of 11.5 Gbit/s using a transmitter with an optical power of 660 mW. Our results pave the way towards next-generation LiFi systems based on high-power VCSEL-arrays.
Beam-Steered Channel Measurement at 160 GHz in an Industrial Environment
Beam-steered channel measurements were analyzed and evaluated on the basis of identified beam pair realizations regarding MIMO capabilities, macro-diversity gains and blockage effects for a multi-transmitter industrial sub-terahertz communication...
Angle-Resolved Channel Measurements at 28 and 160 GHz in Open Office Environment
Explore how 28 and 160 GHz radio channels really behave in an industrial-style open office. Using angle-resolved measurements at 135 positions, this paper extracts path loss, delay and angular spreads, validates 3GPP models, and quantifies...
Adaptive Change-Point Detection in S-RISnet-Assisted Wireless Networks
This paper proposes Adaptive S-RISNet, a scalable RIS configuration framework that leverages statistical CSI and change-point detection to update phase shifts only when necessary. The method achieves near-optimal performance while drastically...
Catalytically active plate heat exchanger for flexible hydrogen release from perhydro benzyltoluene
A catalytic plate reactor derived from the design of conventional plate heat exchangers was used for the continuous and dynamic dehydrogenation of perhydro benzyltoluene, a LOHC. The surface of heat exchanger plates has been catalytically...
Software for dataset-wide XAI: From local explanations to global insights with Zennit, CoRelAy, and ViRelAy
The predictive capabilities of Deep Neural Networks (DNNs) are well-established, yet the underlying mechanisms driving these predictions often remain opaque. The advent of Explainable Artificial Intelligence (XAI) has introduced novel...
Short Range Optical Wireless Communication at 67.8 Gbit/s using a Multiaperture VCSEL
We demonstrate a point-to-point optical wireless communication link for fixed wireless access scenarios using a multiaperture VCSEL. At 5 meters distance, a record net data rate of 67.8 Gbit/s is reached after LDPC FEC.
