The initial coarse alignment via membrane folding was 2 mum, which gives a coarse-to-fine alignment improvement of more than 60times. Alignment was achieved by using the attractive force between arrays of nanomagnets patterned on the membranes before folding. Optical gratings and circular voids forming a 3D photonic crystal-like structure were patterned before membrane release and self-aligned after folding. Alignment performance was maintained during multiple folding and unfolding operations.","PeriodicalId":402931,"journal":{"name":"2008 IEEE/LEOS International Conference on Optical MEMs and Nanophotonics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2008-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128964078","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}

Pure paraboloid can focus light without aberration a one of the ideal mirror surfaces. In the conventional method, varifocal mirror generates an approximate spherical surface or a paraboloid-like surface by applying a distributed load to the central part of the mirror with parallel plate electrodes. In this study, the micromirror is deformed only by applying a bending moment to the circumference of the mirror in order to generate an ideal paraboloid. The proposed mirror was fabricated from SOI wafer. The deviation of the varifocal mirror from the ideal paraboloid was measured to be smaller than 5 nm for the 400 mum diameter mirror with the focal lengths from the infinity to 24 mm at the voltages from 0 to 215 V.","PeriodicalId":402931,"journal":{"name":"2008 IEEE/LEOS International Conference on Optical MEMs and Nanophotonics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2008-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114455214","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}

A hexagonal 61-element unimorph actuator array was produced with an Al or Au reflective layer over the backside of the diaphragm. In order to reduce the dead space for the lead lines between the actuators, they were prepared on the polyimide insulating layer.
