Title: | Photopolymeric films with highly tunable refractive index modulation for high precision diffractive optics | Authors: | ZANUTTA, Alessio Orselli, Enrico Fäcke, Thomas BIANCO, ANDREA |
Issue Date: | 2016 | Journal: | OPTICAL MATERIALS EXPRESS | Number: | 6 | Issue: | 1 | First Page: | 252 | Abstract: | The design and manufacturing of high efficiency and reliable volume phase holographic optical elements require photosensitive material where it is possible to finely control the refractive index modulation. Bayfol HX photopolymers show this feature together with other interesting advantages, in particular the self-developing and the large refractive index modulation. In this paper, the design of Volume Phase Holographic Gratings (VPHGs) is reported underlying the relationship of gratings' performances with the refractive index modulation. The trend of this property with the change of the laser power density and the ratio of the two writing beams is shown. Based on these results, VPHGs for astronomical instrumentation have been designed and manufactured. | URI: | http://hdl.handle.net/20.500.12386/25213 | URL: | https://www.osapublishing.org/ome/abstract.cfm?uri=ome-6-1-252 | ISSN: | 2159-3930 | DOI: | 10.1364/OME.6.000252 | Bibcode ADS: | 2016OMExp...6..252Z | Fulltext: | open |
