    Journal of Lightwave Technology
    A high-speed plasmonic barium titanate (BTO, BaTiO3) Mach-Zehnder modulator is presented. We combine nanoscale plasmonics with BTO as solid-state active material and silicon nitride (SiN) for versatile and low loss waveguiding, and integrate them in a monolithic platform. We demonstrate a plasmonic BTO modulator processed onto foundry-produced SiN. The 15 μm long high-speed modulator features a flat electro-optic frequency response up to 70 GHz and is expected to be flat way beyond. A low VπL product of 144 Vμm is shown. Data experiments reaching 216 Gbit/s with a 216 GBd 2PAM signal and 256 Gbit/s with a 128 GBd 4PAM signal are demonstrated. The merger of the versatile silicon nitride platform with high-speed plasmonics using the highly nonlinear ferroelectric BTO is an attractive solution as a future Tb/s optical interconnect platform.
  • Closed-Loop Control of Photonic Ring Resonators by Means of Photo-Thermal Plasmonic Sensors
    Item type: Journal Article
    Di Tria, Alessandro; Martinez, Andres; Grimaldi, Vittorio; et al. (2024)
    Journal of Lightwave Technology
    This paper highlights the effectiveness of photo-thermal plasmonic sensors in enabling real-time closed-loop stabilization of photonic devices. To assess the waveguided optical power, the in-line detector leverages the photo-thermal resistance variation of a micrometric plasmonic strip in contact with the waveguide. The generated signal is used to lock to resonance a ring resonator against wavelength and temperature variations, in a silicon-based technology. Thanks to the high sensitivity of the detector and its limited penalty on the waveguide loss, automatic re-tuning of the ring resonator with a recovery time of 20 ms has been successfully achieved. The micrometric dimensions of the sensor, its technological simplicity, and the delivered signal (proportional to the optical power) make the photo-thermal plasmonic sensor an attractive in-line candidate for closed-loop control of optical devices, regardless of the technology employed for the photonic chip fabrication.

  • All-optical Mach-Zehnder interferometer wavelength converters and switches with integrated data- and control-signal separation scheme
    Item type: Journal Article
    Leuthold, Juerg; Besse, Pierre-André; Gamper, Emil; et al. (1999)
    Journal of Lightwave Technology
    All-optical Mach-Zehnder interferometer (MZI) wavelength converters and switches with monolithically integrated data- and control-signal separation schemes are reported. Two schemes to separate the data from the strong control signals are discussed. A first dual-order mode configuration uses modes of different symmetry for the data and control signals. A second configuration uses additional MZI's to separate the two signals. The control-signal separation permits to operate the devices with copropagating data and control signal without distortion of the control signal in the data-signal output. Copropagative operation allows for shorter switching windows compared to the counterpropagative operation. Further, this concept enables cascading of several devices since the control signal is filtered out and does not disturb the signal processing in a next cascade of devices. The all-optical switches are characterized under static and dynamic 10 GHz conditions.
