| Abstract: | Gratings with varible periodes (chirped gratings) have been fabricated by recor-ding the interference pattern of a converging beam. The simple system ensures that the two beams forming the holographic grating have equal intensities. This is crucial for obtaining high aspect-ratio structures. We use a He-Ne laser beam for observing the efficiency of diffration grating as development proceeds. |
