    • Anti-Reflecting Surfaces Using Two-layer Motheye Structures for Spinel Ceramic Windows 

      Tu, Chaoran; Menyuk, Curtis R. (2018-09)
      We design and optimize a two-layer pyramid motheye structures for long wavelength MgAl₂O₄ spinel ceramic windows. We show that a two-layer pyramid motheye structure can achieve average transmission of 98.96% from 0.5 µm to 5 µm.

    • Third-Order Nonlinear Optical Properties of ALD Grown TiO₂ Films by Thermally Managed Z-scan Method 

      Basaldua, I.; Burkins, P.; Kuis, R.; Kropp, J. A.; Gougousi, T.; Johnson, A. M. (Optical Society of America, 2018)
      Thermally managed Z-scan performed on ALD grown TiO₂ films demonstrated n₂ values of 1.7×10⁻¹¹ and 1.94 × 10⁻¹⁰cm²/W for films grown at 100°C and 250°C, respectively – greater than 1000X that of other growth methods.
