在这封信中，我们提出并实验证明了一种基于环形孔径几何的彩色滤光片在可见光范围内工作。该装置是通过在适合传输测量的金膜上配置一组环形孔来构建的。通过对孔径尺寸的精确几何控制，实现了共振峰的有效微调。通过不同大小的环形孔的选择性传输导致传输电磁波的连续颜色调谐。这可能会在高清显示、光学滤波器、超快开关和生物传感中找到潜在的应用。(C) 2011年美国物理研究所。(doi: 10.1063/1.3608147)
In this letter, we propose and experimentally demonstrate a color filter based on an annular aperture geometry working in the visible range. The device is built by configuring an array of annular apertures in a gold film suitable for transmission measurement. We show effective fine tuning of resonance peaks through precise geometric control of the aperture dimensions. Selective transmission through annular apertures of various sizes leads to continuous color tuning of transmitted electromagnetic waves. This may find potential for application in high-definition displays, optical filters, ultrafast switching, and bio-sensing. (C) 2011 American Institute of Physics. [doi:10.1063/1.3608147]
