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.
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...

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...
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...
Introducing AI practitioners to international standards through online competitions
This Comment analyzes a global online landslide classification challenge to examine whether AI competitions can help participants engage with international standards. The results show that while technical innovation was strong, awareness of...
Evaluation of a WR6.5 Rotary Joint with two 3D-printed TE01 Mode Transducers
This paper explores a WR6.5 rotary joint based on two 3D-printed mode transducers. Tests from 140 to 170 GHz show about 2 dB of insertion loss across a 16 GHz usable band (145-161 GHz) and less than 15 degree of phase variation, validating 3D...
Dual-Beam Planar D-Band Antenna Array: Filtering Patch Antennas and Dielectric Lens
A hybrid analog beamforming at D-band is demonstrated by integration between an antenna array and a dielectric lens. The beam is collimated on one plane by the antenna array, and on the other by the elliptical lens profile. The antenna element is...
