    • Photoswitchable molecular dipole antennas with tailored coherent coupling in glassy composite

      Elbahri, Mady; Zillohu, Ahnaf Usman; Gothe, Bastian; Hedayati, Mehdi Keshavarz; Abdelaziz, Ramzy; El-Khozondar, Hala J.; Bawa'aneh, Muhammad S; Abdelaziz, Moheb; Lavrinenko, Andrei; Zhukovsky, Sergei; Homaeigohar, Shahin (Nature Publishing Group, 2015)
      Here, we introduce the first experimental proof of coherent oscillation and coupling of photoswitchable molecules embedded randomly in a polymeric matrix and acting cooperatively upon illumination with UV light. In particular, ...

    • Photo‐driven Super Absorber as an Active Metamaterial with a Tunable Molecular‐Plasmonic Coupling

      Hedayati, Mehdi Keshavarz; Javaheri, Mojtaba; Zillohu, Ahnaf Usman; El-Khozondar, Hala J.; Bawa'aneh, Muhammad S; Lavrinenko, Andrei; Faupel, Franz; Elbahri, Mady (2014)
      An optically driven metamaterial with a photoswitchable weak and strong molecular‐plasmonic coupling is demonstrated. In this active perfect absorber, the absorption band can be broadened more than 150 nm (split with an ...
