    • Coherent mode coupling in highly efficient top-emitting OLEDs on periodically corrugated substrates 

      Schwab, Tobias; Fuchs, Cornelius; Scholz, Reinhard; Zakhidov, Alexander; Leo, Karl; Gather, Malte Christian (2014-03-25) - Journal article
      Bragg scattering at one-dimensional corrugated substrates allows to improve the light outcoupling from top-emitting organic light-emitting diodes (OLEDs). The OLEDs rely on a highly efficient phosphorescent pin stack and ...
    • Fabrication of low loss dispersion engineered chalcogenide photonic crystals 

      Spurny, Marcel; O'Faolain, Liam; Bulla, Douglas A. P.; Luther-Davies, Barry; Krauss, Thomas F. (2011-01-31) - Journal article
      We demonstrate low loss photonic crystal waveguides in chalcogenide (Ge33As12Se55) glasses. The measured losses are as low as 21dB/cm. We experimentally determine the refractive index of the thin film chalcogenide glass ...
    • Thin high numerical aperture metalens 

      Kotlyar, V. V.; Nalimov, A. G.; Stafeev, S. S.; Hu, Changyu; O'Faolain, L.; Kotlyar, M. V.; Gibson, D.; Song, S. (2017-04-03) - Journal article
      We designed, fabricated, and characterized a thin metalens in an amorphous silicon film of diameter 30 µm, focal length equal to the incident wavelength 633 nm. The lens is capable of simultaneously manipulating the state ...
