    Well-controlled yet practical systems that give access to interference effects are critical for established and new functionalities in ultrafast signal processing, quantum photonics, optical coherence characterization, ...
  • Guéna, J.; Weyers, S.; Abgrall, M.; Grebing, C.; Gerginov, V.; Rosenbusch, P.; Bize, Sebastien; Lipphardt, B.; Denker, H.; Quintin, N.; Raupach, S.M.F.; Nicolodi, D.; Stefani, F.; Chiodo, N.; Koke, S.; Kuhl, A.; Wiotte, F.; Meynadier, F.; Camisard, E.; Chardonnet, C.; Le Coq, Y.; Lours, M.; Santarelli, G.; Amy-Klein, A.; Le Targat, R.; Lopez, O.; Pottie, P.-E.; Grosche, G. (Bristol : Institute of Physics Publishing, 2017)
    We report on the first comparison of distant caesium fountain primary frequency standards (PFSs) via an optical fiber link. The 1415 km long optical link connects two PFSs at LNESYRTE (Laboratoire National de métrologie ...
  • Hachicha, B.; Overmeyer, Ludger (Bellingham, WA : S P I E - International Society for Optical Engineering, 2016)
    Polymer optical waveguides, especially single-mode waveguides are increasingly used for short distance communication, as well as for sensing applications. The realization of a working communication route requires different ...
  • Zheng, Yulong; Bremer, Kort; Roth, Bernhard (Basel : MDPI AG, 2018)
    In this work we investigate the strain, temperature and humidity sensitivity of a Fiber Bragg Grating (FBG) inscribed in a near infrared low-loss multimode perfluorinated polymer optical fiber based on cyclic transparent ...
  • Bluemel, S.; Bastick, S.; Staehr, R.; Jaeschke, P.; Suttmann, O.; Overmeyer, L. (Amsterdam : Elsevier B.V., 2016)
    For the development of a robot based laser cutting process of automotive 3D parts consisting of carbon fibre reinforced plastics (CFRP), investigations with a newly developed fibre guided nanosecond pulsed laser with an ...
  • Schlangen, Sebastian; Bremer, Kort; Zheng, Yulong; Böhm, Sebastian; Steinke, Michael; Wellmann, Felix; Neumann, Jörg; Roth, Bernhard; Overmeyer, Ludger (Basel : MDPI AG, 2018)
    Long-period fiber gratings (LPGs) are well known for their sensitivity to external influences, which make them interesting for a large number of sensing applications. For these applications, fibers with a high numerical ...

    Mode division multiplexing (MDM) could bring a technological progress in the field of optical telecommunication by increasing the data transmission bandwidth. A key challenge for enabling MDM lies in manufacturing of ...
  • Ahrens, Andreas; Sandmann, Andre; Bremer, Kort; Roth, Bernhard; Lochmann, Steffen (Bellingham, WA : S P I E - International Society for Optical Engineering, 2015)
    In this paper multiple-input multiple-output (MIMO) signal processing is investigated for fibre optic sensor applications. A (2 × 2) MIMO implementation is realized by using lower-order and higher-order mode groups of a ...
  • Kelb, Christian; Körner, Martin; Prucker, Oswald; Rühe, Jürgen; Reithmeier, Eduard; Roth, Bernhard (Basel : MDPI AG, 2017)
    We present a full-polymer respiratory monitoring device suited for application in environments with strong magnetic fields (e.g., during an MRI measurement). The sensor is based on the well-known evanescent field method ...
  • Flury, Jakob (Bristol : Institute of Physics Publishing, 2016)
    Quantum metrology enables new applications in geodesy, including relativistic geodesy. The recent progress in optical atomic clocks and in long-distance frequency transfer by optical fiber together pave the way for using ...
  • Alwis, Lourdes Shanika; Bremer, Kort; Weigand, Frank; Kuhne, M.; Helbig, Reinhard; Roth, Bernhard (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)
    An optical fibre-based strain sensor embroidered to a functionalised carbon structure (FCS) that can be used for structural health monitoring (SHM) is introduced. The aim of the design is not only to monitor strain, but ...
  • Hinney, Jakob; Prasad, Adarsh S.; Mahmoodian, Sahand; Hammerer, Klemens; Rauschenbeutel, Arno; Schneeweiss, Philipp; Volz, Jürgen; Schemmer, Max (College Park, Md. : APS, 2021)
    We observe that a weak guided light field transmitted through an ensemble of atoms coupled to an optical nanofiber exhibits quadrature squeezing. From the measured squeezing spectrum we gain direct access to the phase and ...
