Simulation and analysis of plasmonic sensor in NIR with fluoride glass and graphene layer
Source abstract
Abstract
Abstract A calcium fluoride (CaF 2 ) prism based plasmonic biosensor with graphene layer is proposed in near infrared region (NIR) of operation. The stacking of multilayer graphene is considered with dielectric interlayer sandwiched between two graphene layers. Excellent optical properties of CaF 2 glass and enhanced field at the graphene-analyte interface are intended to be exploited for proposed sensor structure in NIR spectral region. Performance parameters in terms of field enhancement at interface and figure of merit ( FOM ) are analyzed and compared with those of conventional SPR based sensor. It is demonstrated that the same sensor probe can also be used for gas sensing with nearly 3.5–4 times enhancement in FOM , compared with conventional sensor. The results show that CaF 2 based SPR sensor provides much better sensitivity than that based on other glasses.
