Photonic crystal supporting high frequency sensitivity self-collimation phenomenon and design method and use thereof
A photonic crystal supporting highly frequency-sensitive self-collimation phenomenon, which is formed by at least two kinds of materials, and has a periodic distribution of refractive index, the photonic crystal has straight equi-frequency contours or flat equi-frequency surfaces in a certain band in the first Brillouin zone of wave-vector space, and the frequency-sensitivity of self-collimation is at least 50 times higher than the change rate of curvatures of the equi-frequency contours or the equi-frequency surfaces with frequencies in a vacuum.
