    • Digital OPLL-based distributed Brillouin sensing system in optical fibers 

      Chin, Sanghoon; Denis, Séverine; Kundermann, Stefan; Brasch, Victor; Lecomte, Steve (2022-05-23)
      A digital optical phase-locked loop (OPLL) has been implemented to develop a distributed Brillouin sensing system in optical fibers. In our experiment, two commercial semiconductor lasers are phase-locked to each other ...
    • Stability of Lithium Niobate Integrated Photonics in Nonlinear and Metrology Applications 

      Obrzud, Ewelina; Sattari, Hamed; Voumard, Thibault; Choong, Gregory; Denis, Séverine; Leo, Jacopo; Wildi, Thibault; Dubochet, Olivier; Lecomte, Steve; Herr, Tobias; Ghadimi, Amir; Brasch, Victor (2021-12-07)
      We demonstrate that lithium niobate integrated photonics allows for reliable nonlinear applications under continuous femtosecond laser irradiation. Over 400 hours, a stable octave-spanning supercontinuum plus second-harmonic ...

      We demonstrate that lithium niobate integrated photonics allows for reliable nonlinear applications under continuous femtosecond laser irradiation. Over >100 hours, a stable octave-spanning supercontinuum plus second-harmonic ...
    • Stable and compact RF-to-optical link using lithium niobate on insulator waveguides 

      Obrzud, Ewelina; Denis, Séverine; Sattari, Hamed; Choong, Gregory; Kundermann, Stefan; Dubochet, Olivier; Despont, Michel; Lecomte, Steve; Ghadimi, Amir H.; Brasch, Victor (2021-12-01)
      Optical frequency combs have become a very powerful tool in metrology and beyond, thanks to their ability to link radio frequencies with optical frequencies via a process known as self-referencing. Typical self-referencing ...
