However, the availability of polymer optical fibers (POFs) makes it possible to further simplify mirror preparation operations so that massive production of such low cost side couplers is feasible. Both the conventional reflection and the total internal reflection can easily be implemented through mirrors formed inside a POF using mechanical or other types of etching techniques. We show two conventional micro-mirrors which an embedded into a POF through a serious of microcutting, masking, metallic coating, and polymer refilling. A mirror can be formed either by satisfying the total internal reflection condition of the etched interface or by metal deposition using a conventional metallic mirror coating process.","PeriodicalId":332726,"journal":{"name":"Conference Proceedings LEOS'96 9th Annual Meeting IEEE Lasers and Electro-Optics Society","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127308555","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}

Here we try to determine the cavity loss by varying the amount of light fed back to the VCSEL using an external mirror. The tested VCSEL consists of a superlattice active region surrounded by AlAs/Al/sub 0.3/Ga/sub 0.7/As distributed Bragg reflectors. The nonlinear gain effect is introduced in estimating the internal parameters of VCSELs. Since most VCSELs operate at a carrier density much higher than the transparency level, the nonlinear gain effect should be nonnegligible and be considered. Therefore, this method is appropriate even for a large threshold-gain (like the VCSEL) and/or a large amount of the feedback light (more than a few percents).","PeriodicalId":332726,"journal":{"name":"Conference Proceedings LEOS'96 9th Annual Meeting IEEE Lasers and Electro-Optics Society","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128913323","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}
