As a novel application of silicon-based integrated optics, results from a proposed compact Mach-Zehnder interferometer are presented. The deposition of a ZnO thin-film transducer upon the reference arm of the interferometer transforms this optically passive device into a device with active sinusoidal phase modulation.
Cover: The fabrication of microparts, as those shown in the figure, for the production of scaffolds by means of robotic microassembly is challenging due to their small size and complex 3‐D shape. To facilitate the microassembly process, another challenge is the requirement that the parts need to be stably fixed on the wafer but at the same time easily removed by the microgripper. Currently, SU‐8, a biocompatible material, is used to test the feasibility of the microassembly. Further details can be found in the Review by H. Zhang, D. W. Hutmacher,* F. Chollet, A. N. Poo, and E. Burdet on page 477.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
