Graphene Plasmonics – A Beyond 100 GHz Technology
(2023)2023 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC)Novel approaches towards new generations of graphene plasmonic modulators and detectors with responses of 500 GHz and beyond are introduced. Important performance parameters such as losses, efficiency or responsivity are addressed by combining the technologies.Other Conference Item -
Low-Loss Graphene Organic Hybrid Phase Modulators
(2022)OSA Technical Digest ~ Conference on Lasers and Electro-OpticsUltra-short, low-loss graphene-organic hybrid phase modulators are introduced. 20 Gbit/s PAM-2 and PAM-4 data modulation are demonstrated with devices of 25 μm length and on-chip losses of 0.86 dBOther Conference Item -
Integrated Photonic-Electronic Memristors
(2022)OSA Technical Digest ~ Conference on Lasers and Electro-OpticsWe integrate memristors in a silicon photonic/plasmonic platform and demonstrate modulators, photodetectors and electronic devices complemented with memory effect. The demonstrated memristors could be the key photonic building blocks in hybrid photonic-electronic neuromorphic chips.Other Conference Item -
Metallic Grating Couplers-Broadband and Efficient
(2021)OSA Technical Digest ~ Conference on Lasers and Electro-OpticsMetallic grating couplers can be extremely broadband and efficient. In this work, we investigate an all-plasmonic fiber-to-chip coupler with a coupling efficiency of-2.7 dB and an optical 3-dB passband of 300 nm.Other Conference Item -

Investigation of light-controlled filament dynamics in an electro-optical memristive photodetector
(2019)Proceedings of SPIE ~ Integrated Optics: Design, Devices, Systems, and Applications VThe atom marks the ultimate scaling limit of Moore’s law, which is why atomic scale devices have attracted significant research interests from the electronics industry. To allow efficient co-integration of electronics and photonics, key components such as photodetectors [1] and modulators [2] should match the footprint of electronic devices. Here we demonstrate the first atomic-scale plasmonic photodetector where atoms rather than electrons ...Other Conference Item
