We reported the p-OTDR waveforms were fitted well by modified Mueller matrixes assuming scattering by cloud of non-spherical particles. We realized a PMD measurement based on a novel p-OTDR JME (Jones matrix eigenvalue) method. The measured PMD was consistent with that of JME standard measurement using transmission-type polarimetry. In this paper, we confirm the reliability of this novel PMD measurement method by repeated comparisons with a standard measurement scheme. However, it is desirable to improve signal to noise ratio and algorithm using correlation, and to find direct evidence for non-spherical Rayleigh backscattering.","PeriodicalId":445290,"journal":{"name":"Proceedings of 2005 IEEE/LEOS Workshop on Fibres and Optical Passive Components, 2005.","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124575549","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}

Microlens array to substrate positioning by means of vision and of active alignment was employed for multi-mode fibers and single-mode fibers, respectively. A low-cost adhesive bonding technology was developed for attaching the microlens arrays to the substrates. Optical coupling losses (per lens transition) of well below 1 dB for multi-mode fibers, and below 0.5 dB for single mode fibers over 12 channels for 850 nm, 1300 nm and 1550 nm wavelength were achieved. Stable operation of the fiber/microlens assemblies during preliminary temperature cycling tests has been demonstrated.

MEMS failure mechanisms are quite diversified, due to the very nature of these components. If sticking, particle contamination, and ESD (electrostatic discharges) are often mentioned, other, more exotic effects do exist, which often are not well understood. MEMS packaging plays an essential role in protecting the microsystems from the external world: and devising a good package is often the key to a successful application. Wafer level (WL) packaging offers an interesting alternative for MEMS, and for this reason has often been proposed. However, ensuring a good WL sealing requires temperatures above 300-400 /spl deg/K, which may prove detrimental to some systems. An MOEMS example is discussed in detail, together with the possible solutions.","PeriodicalId":445290,"journal":{"name":"Proceedings of 2005 IEEE/LEOS Workshop on Fibres and Optical Passive Components, 2005.","volume":"166 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115320571","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}
