Fabrication of uniform diffraction gratings using laser interference lithography for simultaneous measurement of refractive index

Abstract: sThe refractive index is one of the important optical properties. Many researchers have studied various methods of measuring refractive index. In this paper, we can easily measure the refractive index of liquids by using diffraction gratings fabricated by flat-top laser interference lithography. Using the diffraction grating for the measurement of the refractive index has the advantage of a wide measurement range. To fabricate the diffraction gratings, we suggest a special laser manufacturing method named flat… Show more
