Photonic Crystal Biosensor Using Surface Plasmon Resonance Effect

Article Preview

Abstract:

We have proposed a biosensor using a one-dimensional (1D) photonic crystal with surface plasmon resonance (SPR) effect. The wavelength interrogation method has been used to study the performance of the sensor. Numerical simulations based on rigorous coupled wave analysis (RCWA) method show that the sensitivity of the optimized sensor is 137 nm/RIU (per refractive index unit).
