We present a qubit-based clock drift correction method with low computational requirements, that demonstrates a performance equal to a clock drift correction via a dedicated clock channel. Our method enables stable long-term operation as well as...

Live rerouting of quantum key distribution links poses new synchronization challenges. We demonstrate the seamless handling of multi-minute channel interruptions and fiber length changes exceeding 100 km during live system operation and over...

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.

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...

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...

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...

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 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...

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...

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...
