Broadband suspended lithium tantalate Mach-Zehnder modulator achieving a 460 Gbit/s net data rate
Zihan Li, Alexander Kotz, Adrian Schwarzenberger +2
Thin-film lithium tantalate photonic integrated circuits have recently been demonstrated as a promising next-generation electro-optic platform, offering favorable properties includ…
Low voltage and high-bandwidth thin-film lithium tantalate modulator on a silicon dioxide substrate
Zihan Li, Alexander Kotz, Adrian Schwarzenberger +2
Modern communication networks demand ever-increasing transmission bandwidth, placing stringent requirements on low-cost, high-performance electro-optic modulators. Substantial adva…
First Sub-MeV Dark Matter Search with the QROCODILE Experiment Using Superconducting Nanowire Single-Photon Detectors
Laura Baudis, Alexander Bismark, Noah Brugger +15
We present the first results from the Quantum Resolution-Optimized Cryogenic Observatory for Dark matter Incident at Low Energy (QROCODILE). The QROCODILE experiment uses a microwi…
Heterogeneously integrated lithium tantalate-on-silicon nitride modulators for high-speed communications
Jiachen Cai, Alexander Kotz, Hugo Larocque +7
Driven by the prospects of higher bandwidths for optical interconnects, integrated modulators involving materials beyond those available in silicon manufacturing increasingly rely…
