    Opt Express 19:10029-40. 2011
    ..We also show that there is a fundamental constraint between the spectral sensitivity and quality factor in such multi-mode sensing approach...

    Ginzton Laboratory, Stanford University, Stanford, CA 94305, USA
    Proc Natl Acad Sci U S A 107:17491-6. 2010
    ..Our theory reveals that the conventional limit can be substantially surpassed when optical modes exhibit deep-subwavelength-scale field confinement, opening new avenues for highly efficient next-generation solar cells...

    Nano Lett 9:279-82. 2009
    ..Our experimental data agree very well with simulation. The a-Si:H nanocones function as both absorber and antireflection layers, which offer a promising approach to enhance the solar cell energy conversion efficiency...

    E L Ginzton Laboratory, Geballe Laboratory for Advanced Materials GLAM, Stanford University, Stanford, California 94305, USA
    Nano Lett 9:235-8. 2009
    ..We find excellent agreement between electromagnetic simulations of the design and confocal measurements on manufactured structures. We provide guidelines for lens design and show how actual lens behavior deviates from simple theory...
