Quantum fiber-pigtail

A scanning electron micrograph (SEM) of a conical photonic wire containing quantum dots, which has been directly connected to the core of an optical fiber. This so-called “quantum fiber-pigtail” may be useful in the context of quantum information or scanning probe microscopy. The work grew out of an original idea by Dr. Mathieu Munsch and Dr. Jean Teissier, from the Warburton and Maletinsky Groups respectively. Ph.D. student Davide Cadeddu from our group carried out the experiments and Dr. Munsch led the project. A movie showing the fabrication process can be found here.

  • Bike Tour 2018

    On Friday, May 11th, 2018, the group went on a day-long bicycle tour of nearby Alsace, France.

  • Davide, Martino, and the Probe

    Prof. Poggio and Ph.D. student Davide Cadeddu are shown here with our custom-made 3He scanning probe microscope.

  • Nanowires as Scanning Force Sensors

    A new type of atomic force microscope (AFM) uses nanowires as tiny sensors. Unlike standard AFM, the device with a nanowire sensor enables measurements of both the size and direction of forces.

  • SNI Video 2014

    In December 2014, the group was featured in a Swiss Nanoscience Institute (SNI) video on the Masters and Ph.D. school on nanoscience here at the University of Basel. (Video)
