Films of polymer fiber cladding were tested at 250°C for periods of up to 10 hours. During this heating, significant changes in Young's modulus, refractive index, weight, hardness, strength, elongation and Tg were observed, although some changes were much less than others. In our 150 °C study [2], in general, polymers with higher concentrations of fluorine, and thus lower refractive indices, were observed to perform better at higher temperatures for extended periods. We have seen results in some parameters at the much higher temperature of 250°C where the behavior is similar, but this is not always the rule. In some tests, such as refractive index change at 633 and 852 nm, materials with less fluorine were observed to demonstrate lower index change. As the degradation temperature of all the polymers examined in this paper falls between 250 and 280°C, that the changes in materials occur are not surprising. While these polymers cannot function at 250°C for long periods, it is possible to expose them for much shorter periods of time without apparent damage. Such polymers have been exposed to high temperatures for a few minutes while being successfully jacketed with extruded materials (including Tetzel®) [3]. Certain results at 4 and 6 hours showed small changes. A sensor or other fiber device might be able to function in these temperatures for an hour or more without the coating or device breaking down.","PeriodicalId":174592,"journal":{"name":"2011 IEEE Avionics, Fiber- Optics and Photonics Technology Conference","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124838804","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 the past 10 years, many Optoelectronic component and subsystem companies disappeared after the dot-com bust. This forced the remaining companies to focus tactically on products customers would commit to buy. Few products were newly developed without a waiting market or customer commitment and development budgets where significantly reduced. Companies no longer developed products just to fill out their product portfolios. These designs and product roadmaps had little to no influence from the defense or military arena. Further complicating the issue was the widening gap in the fundamental technology - with many military applications using multimode and the commercial telecom market using single mode. Furthermore since many military programs can be relatively low volume in comparison to commercial applications, the influence of these military applications on products being developed was minimal. On the military side, there was limited understanding and awareness of the roadmaps driving the commercial market or a way of influencing these developments. Closer coupling of future military needs with component manufacturers would benefit both. Many military customers are reluctant to share future directions due to competitive or security concerns. By utilizing COTS, minimal information needs to be shared on the application or integration and deployment costs can be reduced.","PeriodicalId":174592,"journal":{"name":"2011 IEEE Avionics, Fiber- Optics and Photonics Technology Conference","volume":"217 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121731147","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}
