The key to attaining high Q and to stabilizing resonance frequency of resonators is to effectively decouple the pull-in scheme and mechanical boundary conditions of resonators. In this work, CMOS-MEMS resonators with deep-submicron gaps have been measured with motional impedance down to 172kΩ and Q's greater than 2,000. In addition, such a resonator monolithically integrated with CMOS amplifier, totally occupying die area of only 300µm × 130µm, was also tested with enhanced transmission. With such improved performance, this technique may pave a way to realize fully-integrated CMOS-MEMS oscillators, therefore benefitting future single-chip applications.","PeriodicalId":344989,"journal":{"name":"2010 IEEE International Frequency Control Symposium","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125169270","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}

The stability of the most stable lasers is limited by thermal noise of the reference cavities to which the frequency of the laser is locked. Overcoming this limitation is a serious challenge. We discuss an alternative route to ultra-stable light that circumvents the need for an improved reference cavity. The idea is to generate light actively from ultra-cold atoms in a lattice clock. We discuss the physical mechanism underlying this light source, experimental requirements, and key characteristics of the generated light such as its intensity, linewidth, and noise properties.","PeriodicalId":344989,"journal":{"name":"2010 IEEE International Frequency Control Symposium","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130969453","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}

Comparison of vibration mode shapes of the resonators with and without four supporting beams in the modal analysis using finite element analysis indicated that several contour modes vibrating at large amplitude in the corners with frequency lower than that of the Lamé mode get a boost in frequency by the constraint at the corners and resulted in spurious modes to the Lamé mode by temperature shift. Comparison of mode shapes of these unwanted contour vibrating modes with and without truncation at the corners of the square quartz plate indicated another boost in frequency caused by the reduction in mass where the mode vibrates at large amplitude. Four-corner truncated square quartz resonators supported by four beams were designed and fabricated by wet etching process. Measured data of the fabricated resonators made of LQ1T and LQ2T cut quartz plates indicated a zero temperature coefficient and electrical equivalent circuit parameters comparable to those of a fundamental mode Lamé resonators with two point support.","PeriodicalId":344989,"journal":{"name":"2010 IEEE International Frequency Control Symposium","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132439316","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}
