  • Edinger, Pierre, et al. (författare)
  • Reducing Actuation Nonlinearity of MEMS Phase Shifters for Reconfigurable Photonic Circuits
  • 2019
  • Ingår i: 2019 CONFERENCE ON LASERS AND ELECTRO-OPTICS (CLEO). - : IEEE. - 9781943580576
  • Konferensbidrag (refereegranskat)abstract
    • The low power consumption of MEMS actuators enables large-scale reconfigurable photonic circuits. However, insertion loss and actuation linearity need improvement. By simulations and experiments, we analyze the dominating design parameters affecting linearity and suggest improvements.

  • Hansson, Tobias, et al. (författare)
  • Quadratic cavity soliton optical frequency combs
  • 2019
  • Ingår i: 2019 CONFERENCE ON LASERS AND ELECTRO-OPTICS (CLEO). - : IEEE. - 9781943580576
  • Konferensbidrag (refereegranskat)abstract
    • We theoretically investigate the formation of frequency combs in a dispersive second-harmonic generation cavity system, and predict the existence of quadratic cavity solitons in the absence of a temporal walk-off. (C) 2019 The Author(s)

  • Near-Infrared Continuous-Filtering Vernier Spectroscopy in a Flame
  • 2019
  • Ingår i: Conference on Lasers and Electro-Optics. - : IEEE. - 9781943580576
  • Konferensbidrag (refereegranskat)abstract
    • A continuous-filtering Vernier spectrometer based on an Er:fiber femtosecond laser was developed to acquire broadband H2O and OH spectra in a premixed CH4/air flame with 25 ms time resolution and percent precision on concentrations retrieval.

  • Merkl, Philipp, et al. (författare)
  • Ultrafast Transition from Intra- to Interlayer Exciton Phases in a Van Der Waals Heterostructure
  • 2019
  • Ingår i: Optics InfoBase Conference Papers. - 2162-2701. - 9781943580576
  • Konferensbidrag (refereegranskat)abstract
    • The binding energy of interlayer excitons is measured by revealing a novel 1s-2p resonance in the mid infrared. Intralayer excitons transform directly into interlayer species via ultrafast electron tunneling strongly influenced by the stacking angle. (C) 2019 The Author(s)

  • Pereira, Joao, et al. (författare)
  • Poling optical fibers with UV lamp
  • 2019
  • Ingår i: Conference on Lasers and Electro-Optics OSA Technical Digest (Optical Society of America, 2019), paper SM2L.5. - : OSA - The Optical Society. - 9781557528209
  • Konferensbidrag (refereegranskat)abstract
    • Silicate fibers with internal electrodes are optically poled without a laser by side-exposure to radiation from a UV tubular lamp. Electrooptic coefficients χ(2) ~ 0.04 pm/V and Vπ = 810 V are obtained.

  • Sadiek, Ibrahim, et al. (författare)
  • Optical Frequency Comb Photoacoustic Spectroscopy
  • 2019
  • Ingår i: Conference on Lasers and Electro-Optics. - : IEEE. - 9781943580576
  • Konferensbidrag (refereegranskat)abstract
    • We combine for the first time a mid-infrared optical frequency comb Fourier transform spectrometer with cantilever-enhanced photoacoustic detection and measure high-resolution broadband spectra of the fundamental band of methane in a few milliliter sample volume.

  • Coherent Temporal Phase Transfer in Backward Wave Parametric Oscillator at 1.4 mu m
  • 2019
  • Ingår i: 2019 CONFERENCE ON LASERS AND ELECTRO-OPTICS (CLEO). - : IEEE. - 9781943580576
  • Konferensbidrag (refereegranskat)abstract
    • The frequency modulation transfer property of a backward wave optical parametric oscillator is employed to generate compressed near-IR pulses at 1.4 mu m with 1.3ps duration. Limitations to the linear frequency modulation transfer in BWOPO are investigated.
