Binary quasi-periodic hole array with the completely suppression of high order diffractions


Spectral measurement plays a central role in nearly allaspects of modern optical science and engineering. In a wide spectral measurement, the unwanted higher order diffraction overlaps the first one, which greatly degrades precision of analysis. And the sinusoidal transmission gratings with only 0-order and +1/-1 order diffractions are more difficult to… (More)
