The effect is manifest by both a steady state power dependent transfer of as much as 30% optical energy between orthogonally polarized modes as well as a transient regenerative switching between these modes seen only in x-cut samples subjected to continuous optical throughput at the above power levels for a period of 8-24 hours. A model of the observations is proposed based on photore f ract ive perturbations.","PeriodicalId":302681,"journal":{"name":"Sixth IEEE International Symposium on Applications of Ferroelectrics","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121074286","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}

In this paper the process of preparation and the characterization of some of these materials are presented. The characterization which is considered is the determination of the resonance frequency dispersion diagrams of narrow parallelepipedic elements and the determination of the thickness and planar modes characteristics. Both kinds of characteristics are derived from the classical tensorial component characterization, the dispersion diagrams are derived by means of a finite-element method simulation. The characterizations of two piezoceramics of each type are presented. The results and the method are discussed and some comments on the application t o ultrasonic transducer design are included.","PeriodicalId":302681,"journal":{"name":"Sixth IEEE International Symposium on Applications of Ferroelectrics","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124282728","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}
