摘要：
A finite element analysis of biosensor-based dual-core photonic crystal fiber is conducted using surface plasmon resonance model and is presented in this article. Calculated wavelength sensitivity of the sensor is around 10,000 nm/RIU and 5000 nm/RIU for x-polarization and y-polarization, respectively, when analyte refractive index is 1.34. Amplitude sensitivity for x-polarization and y-polarization is 334 RIU-1 and 394 RIU-1, respectively. Resolution for both polarizations is 2 x 10(-5) RIU. Consequently, the proposed biosensor can detect the low-refractive-index biochemical analyte at different wavelengths.
