Because of good solution processing characteristic of the GO to polymer, a GO-polymer saturable absorber (SA) was successfully fabricated. Self-started mode-locking laser performance was investigated comprehensively at different cavity lengths, from 5, 24, to 94 m. The results showed that the pulse duration varies from hundreds of picoseconds to nanoseconds. In addition, the average output power of the mode-locked fiber laser can reach up to 500 mW. Furthermore, it was demonstrated that pulses with large chirps can be more easily amplified to reach high output power.","PeriodicalId":158783,"journal":{"name":"2012 Photonics Global Conference (PGC)","volume":"196 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132193349","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 feed and draw speed generally follows the simplified mass conservation law to draw the fiber to a specific dimension. The preform wall thickness affects the vacuum pressure and furnace temperature that is needed to `flatten' the fiber. The preform wall thickness is directly proportional to the volume of glass inside the neck-down region. The wall thickness of the preform and its dopant will also affect the size of the cladding and core dimension. Finally, some issues associated with the fabrication of Flat Fibers are also observed and discussed, including fabrication of Flat Fibers with non-uniform dimensions, deformed shapes, unwanted airholes and poor quality of the Flat Fibers.","PeriodicalId":158783,"journal":{"name":"2012 Photonics Global Conference (PGC)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123364484","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}

We proposed a novel method for monitoring optical fiber sensor networks using optical frequency-domain reflectometry (OFDR) which provides a narrow spatial resolution that enables us to locate closely separated reflection and discrete sensors such as fiber sensing grating and other microstructure fiber sensors. Moreover, thanks to the inherently coherent detection, a high dynamic range can be realized that allows the measurement of Rayleigh backscattering throughout a fiber network. Namely, OFDR also can monitor distributed fiber sensors By using narrow linewidth laser, OFDR's monitoring range satisfies the requirements for long range optical fiber sensor networks. In our OFDR system proposed, we can achieve to monitor optical fiber sensor networks with measurement range of a few tens of kilometers in a sub-cm spatial resolution.","PeriodicalId":158783,"journal":{"name":"2012 Photonics Global Conference (PGC)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121716735","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}

Then, the shift is traced and determined by the tracing ring through direct voltage supply.

The periodic nanohole structure of the biosensor and the gold coating of the sensor surface produce extraordinary light transmission (EOT) resonances of which the resonance peak shifts proportionately to the change of environment refractive index (RI). Detailed simulations studies were carried out to establish the resonance spectrum and sensitivity in relationship with the nanohole array pitch, diameter and gold thickness for hexagonal lattice arrangement. The plasmonic sensors were fabricated by top down approach utilizing mask-based deep ultraviolet (DUV) lithography. The plasmonic nanohole sensor was tested with a direct coupling method of incident light which allows robust and sensitive sensing platform with minimal alignment requirements. The measured bulk refractive index sensitivity is 409.4 nm/RIU and the surface mass sensitivity is 1.802 nm/ng mm-2.
