>150 GHz Hybrid-Plasmonic BaTiO3-On-SOI Modulator for CMOS Foundry Integration
(2021)Frontiers in Optics + Laser Science 2021A ferroelectric, metal-oxide-semiconductor (MOS) based, hybrid-plasmonic modulator is shown to feature bandwidths of >150 GHz and is tested with 32 Gbit/s NRZ. The device is relying on BaTiO3-on-SOI and potentially offers CMOS compatibility.Conference Paper -
Plasmonic-MZM-based Short-Reach Transmission up to 10 km Supporting >304 GBd Polybinary or 432 Gbit/s PAM-8 Signaling
(2021)2021 European Conference on Optical Communication (ECOC)We employ an ultrabroad-bandwidth plasmonic Mach-Zehnder modulator to demonstrate 10-km IM/DD transmission at a symbol rate of 304-GBd (AIR 293.3-Gbit/s, net 270.0-Gbit/s) realized with a poly-binary modulation scheme, and a line rate of 432-Gbit/s (AIR 383.6-Gbit/s, net 350.4-Gbit/s) using PAM-8.Conference Paper -

Highly Efficient Grating Coupler for Silicon Nitride Photonics with Large Fabrication Tolerance
(2021)Integrated Photonics Research, Silicon and Nanophotonics : part of Advanced Photonics CongressWe demonstrate low-loss fiber-to-chip coupling via a-Si grating couplers on top of SiN waveguides for C-band TE light. The suggested simple scheme is fabrication tolerant and offers a path towards coupling efficiencies above -1 dB.Conference Paper -

Enhanced Stability of Resonant Racetrack Plasmonic-Organic-Hybrid Modulators
(2022)Technical Digest Series ~ 2022 Optical Fiber Communications Conference and Exhibition (OFC)A high-speed and compact plasmonic organic racetrack modulator is shown to be orders of magnitude more robust against operating condition changes compared to resonant modulators based on the plasma dispersion effect while maintaining thermal tunability. Stable operation at 80°C is shown with no degradation.Conference Paper
