Spatial Resolution and Refractive Index Contrast of Resonant Photonic Crystal Surfaces for Biosensing
By depositing a resolution test pattern on top of a Si3N4 photonic crystal resonant surface, we have measured the dependence of spatial resolution on refractive index contrast Δn.Our experimental results and finite-difference time-domain (FDTD) simulations at different refractive index contrasts show that the spatial resolution of our device
