This proposed sensor consists of an Ag-Au bimetallic configuration that integrates the better evanescent field enhancement of silver, the higher resolution in the reflectivity minimum of silver, and the high chemical of gold. In comparison to most convenient SPR sensors which use single gold films, this PC-bimetallic configuration is shown theoretically to possess a narrower resonance width, smaller minimum reflectance and higher sensitivity, which makes it a much better choice to be employed for SPR biosensing applications.","PeriodicalId":114800,"journal":{"name":"Numerical Simulation of Optoelectronic Devices, 2014","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131362901","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 the core radius of multimode fiber is 52.5μm. The simulations show that the resonant wavelengths of 45th~50th propagation modes and their wavelength redshifts due to the ambient refractive index change are all the same. Among the SPR spectrums for different modes, higher order mode will induce deeper notch and larger extinction ratio. By tracing the wavelength shift of the 45th mode, the MFS was optimized. The optimized MFS has 75μm residual fiber thickness and gold film coated on D-shaped multimode fiber. Its average sensitivity of 4989nm/RIU can be attained, which is much higher than 3150nm/RIU of the single mode fiber SPR sensor in the ref.

The excitation light source is a picosecond pulsed infrared laser. A parallel resistance has been introduced to minimize the effect of the equivalent junction series resistance effect. A storage oscilloscope has been used to record the photovoltage of the photodiode. By fitting the exponentially decay curve, the time constant has been obtained which is regarded as the photo-generated minority carrier lifetime of the photodiode. The experimental results show that the carrier lifetime is in the range of 0.7~110 ns at 77 K for the measured detectors of four compositions. The results indicate that the lifetime become longer with the increase of Cd composition.","PeriodicalId":114800,"journal":{"name":"Numerical Simulation of Optoelectronic Devices, 2014","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125554890","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}
