The sensitivity and accuracy of the sensor with and without gratings is observed as well as the effect of changing the grating distance on the resonant wavelength. The findings show that high sensitivity of above 500nm/RIU and a fourfold increase in signal to noise ratio (SNR) is obtained by introducing FBG to the basic fiber optic based SPR structure. Increasing the grating period results in a red shift in the resonant wavelength, thus enabling multiple sensor fabrication on a single fiber optic cable. Simulation of the FBG based SPR sensor to detect alcohol concentration from 0 to 100% in water is also demonstrated.","PeriodicalId":243533,"journal":{"name":"2012 IEEE 3rd International Conference on Photonics","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132946415","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}

A detailed of code construction for a OCDMA system with flexible cross correlation is presented to reduce the effect of interference thus optimizing the code length.

The FCC code can be constructed using a simple tridiagonal matrix compared to other OCDMA codes such as MDW, MQC and MFH, thus the FCC code possesses various advantages including easy code construction and less complexity of encoder/decoder design.

By considering RB effect only, the best crosstalk-to-signal (C/S) ratio for the first case is achieved when the RN is placed either close to the CO or ONU vicinity. And in the second case, when the system has two gain sources (RN and ONU gain), the best C/S ratio is achieved when the RN gain is placed at the center of transmission link. Then, when combining the RB and FR effects, it was demonstrated that the C/S ratio gets worse by almost 1.5 dB in the presence of a strong reflection (r = 30 dB). Furthermore, even if the FR is maintained at the smaller reflectivity and the EDFA gain is increased, the C/S ratio will even get worse when EDFA is placed close to ONU vicinity. It is due to reamplification and re-modulation feedbacks of backreflections that may happen at the preceding and following of the RN gain.","PeriodicalId":243533,"journal":{"name":"2012 IEEE 3rd International Conference on Photonics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131006230","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}
