  • All-Plasmonic sub-Terahertz Wireless Link
    Item type: Conference Paper
    Kulmer, Laurenz; Blatter, Tobias; Zuerrer, Amane; et al. (2025)
    Technical Digest Series ~ Optical Fiber Communication Conference (OFC) 2025
    We offer a highest bandwidth, low-footprint, scalable and low-cost solution for sub-THz wireless communication links. We employ a plasmonic-graphene approach. The solution is tested for transmission of 120 Gbit/s at a carrier-frequency of 285 GHz.
  • Light-Controlled Switching in Electro-Optical Memristors
    Item type: Conference Paper
    Portner, Kevin; Weilenmann, Christoph; Maeder, Alexander; et al. (2022)
    Technical Digest Series ~ Conference on Lasers and Electro-Optics
    We demonstrate a new concept in an electro-optical memristor where a global light stimulus induces non-volatile conductance changes. The optical signal acts as a third, independent stimulation channel, similar to neuromodulators in three-factor learning rules.
  • Plasmonic Modulators for Future High-Capacity Space Communication
    Item type: Conference Paper
    Kulmer, Laurenz; Horst, Yannik Matthias Julius; Blatter, Tobias; et al. (2024)
    Technical Digest Series ~ Frontiers in Optics + Laser Science 2024 (FiO, LS)
    Over a 53km turbulent free-space optical link we have shown data transmission up to 424Gbit/s. These results were enabled by plasmonic modulators offering bandwidths above 100GHz and were extended up to 774Gbit/s in fiber experiments.
  • Pockels Coefficients in Thin-Film Barium Titanate and Lithium Niobate up to 300 GHz
    Item type: Conference Paper
    Chelladurai, Daniel; Kohli, Manuel; Horst, Yannik Matthias Julius; et al. (2023)
    Technical Digest Series ~ Conference on Lasers and Electro-Optics 2023
    The Pockels coefficients in thin-film barium titanate (BTO) and lithium niobate (LN) have been measured for modulating frequencies up to 300 GHz. BTO’s effective nonlinearity is ~10 times larger than LN’s with a small frequency dependence
  • Electro-Optic Coefficient of Thin-Film Lithium Niobate up to 270 GHz
    Item type: Conference Paper
    Chelladurai, Daniel; Kohli, Manuel; Fedoryshyn, Yuriy; et al. (2022)
    Technical Digest Series ~ Frontiers in Optics + Laser Science 2022 (FIO, LS)
    The linear electro-optic coefficient of lithium niobate on insulator (LNOI) thin films has been characterized over a broad range of modulation frequencies from 50 MHz to 270 GHz. A coefficient of 25-30 pm/V was found.
  • Quantum Cascade Laser Spectrometer for Precise Measurements of ¹³CH₃D and ¹²CH₂D₂
    Item type: Other Conference Item
    Prokhorov, Ivan; Tuzson, Béla; Li, Gang; et al. (2023)
    Technical Digest Series ~ Optica Sensing Congress 2023 (AIS, FTS, HISE, Sensors, ES)
    Simultaneous measurements of the five most abundant methane isotopologues is demonstrated using a quantum cascade laser spectrometer. The instrument enables rapid and high-precision analysis of ∆¹³CH₃D and ∆¹²CH₂D₂ in the natural methane samples
  • System-on-Chip Photonic Integrated Circuits in Silicon Photonics and the Role of Plasmonics
    Item type: Conference Paper
    Hoessbacher, Claudia; Bäuerle, Benedikt; De Leo, Eva; et al. (2023)
    Technical Digest Series ~ Optical Fiber Communication Conference (OFC) 2023
    This paper reviews photonic integrated circuits on silicon photonics. We focus on system on chips in applications for optical communications, sensing, and quantum technologies, and outline the role of plasmonics in silicon photonics. (c) 2022 The Author(s)
  • Low-Loss Coupler to Vertical Plasmonic Waveguides
    Item type: Conference Paper
    Chaluvadi, Aditi; Vukovic, Boris; Bisang, Dominik; et al. (2025)
    Technical Digest Series ~ Frontiers in Optics + Laser Science 2025 (FiO, LS)
    We present a coupler from silicon photonic to vertical plasmonic metal-insulator-metal waveguides with a measured efficiency of -1.4 dB at 1550 nm, and an optical bandwidth of more than 100 nm.
  • Microwave Frequency Fiber Interferometry in Submarine Deployed Telecommunication Cables
    Item type: Conference Paper
    Bogris, Adonis; Simos, Christos; Simos, Iraklis; et al. (2025)
    Technical Digest Series ~ Optical Fiber Communication Conference (OFC) 2025
    We operated a microwave frequency fiber interferometer in a telecommunication cable in the Ionian Sea, Greece, for two months. The capability of detecting undersea micro earthquakes (magnitude~1.5), tides and ocean waves is reported.
  • Single GaAs Nanowires for Near-Infrared Spontaneous Parametric Down-Conversion
    Item type: Other Conference Item
    Saerens, Grégoire; Dursap, Thomas; Solntsev, Alexander S.; et al. (2023)
    Technical Digest Series ~ Conference on Lasers and Electro-Optics 2023
    We report 60 GHz/Wm photon pair generation via type-0 spontaneous parametric down-conversion at 1550 nm from individual free-standing GaAs nanowires with sub-450 nm diameter and lengths up to 5 μm.
