    • Optical devices including deterministic aperiodic patterning using spiral arrays exhibit circular symmetry in continuous Fourier space via polarization-insensitive planar diffraction. Far-field diffractive coupling in these structures leads to the formation of scattering resonances with circular symmetry and characteristic vortex behavior carrying orbital angular momentum. Plasmonic nanoparticle arrays with aperiodic spiral geometry can be used in fabrication of optical devices that benefit from polarization insensitive, enhanced light-matter coupling on planar surfaces, such as thin-film solar cells (enhanced light absorption and efficiency), photodetectors (enhanced light emission and efficiency), optical biosensors, and polarization devices.
    • 包括使用螺旋阵列的确定性非周期性图案的光学器件通过偏振不敏感平面衍射在连续傅立叶空间中呈现圆对称性。 这些结构中的远场衍射耦合导致形成具有圆形对称性和携带轨道角动量的特征涡旋行为的散射谐振。 具有非周期螺旋几何形状的等离子体纳米颗粒阵列可用于制造受益于平坦表面上的偏振不敏感,增强的光物质耦合的光学器件,例如薄膜太阳能电池(增强的光吸收和效率),光电检测器(增强的光发射 和效率),光学生物传感器和偏振装置。
