The modulability is obtained through the use of a smart film, a polymer dispersed liquid crystal device (PDLC). Switching of the image pattern of retro-reflected light is demonstrated.

From its plasmonic properties, that kind of structure has a wavelength filtering property. Focusing on this filter characteristic, we have designed a novel MEMS tunable filter based on plasmon photonics. The idea is to make line and space structures and to put one on another vertically such that one would change the gap to control the wavelength filtering effect. By using this structure, we would electromechanically control the surface plasmon. As a preliminary research, we obtained optical properties of line-and-space structures that are crossed, by using the FDTD simulator.","PeriodicalId":421895,"journal":{"name":"2010 International Conference on Optical MEMS and Nanophotonics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115712455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
