Photonic Crystal Supporting High Frequency Sensitivity Self-collimation Phenomenon and Design Method and Use thereof |
| 摘要 |
The present invention provides a photonic crystal supporting high frequency sensitivity self-collimation phenomenon and design method and use thereof. The photonic crystal supporting high frequency sensitivity self-collimation phenomenon has a periodic distribution of refractive index formed by at least two kinds of materials; there exists straight equi-frequency contours or flat equi-frequency surfaces in a certain band in a dispersion space of the photonic crystal, and the change rate of curvatures of the equi-frequency contours or the equi-frequency surfaces with frequencies around the frequency of straight equi-frequency contours or flat equi-frequency surfaces is at least increased at least 50 times than the change rate in vacuum. For the photonic crystal of the present invention is used for controlling diffracted intensity of light beam, detecting refractive index and the like. |
