Fabrication of grating structures with variable period

Alexander C. Livanos, Abraham Katzir, Amnon Yariv

Research output: Contribution to journalArticlepeer-review


Photoresist gratings with variable period have been fabricated by recording the interference pattern of a collimated laser beam with a converging one. The period variation as a function of position, as well as the wavelength dependent focal properties of the gratings, has also been analyzed.
