Modeling and analysis of D–shaped plasmonic refractive index and temperature sensor using photonic crystal fiber

In this study, a D–type photonic crystal fiber (PCF) based surface plasmon resonance (SPR) sensor is proposed for measurement of both refractive index (RI) and temperature. The RI sensing part constructed by deposition silver layer on the plane structure, temperature formed filling nanowire liquid analyte into an elliptical hole in PCF. design then can be used through coupling between core guided modes around nano rod layer. We study characteristic performance sensor. numerical results show that maximal sensitivity terms units (RIU) 6.9 ?m/RIU range 1.33–1.38, 3 nm /°C 27–67 °C.
