Near cut-off wavelength operation of resonant waveguide grating biosensors
Abstract Numerical simulations and analytical calculations are performed to support the design of grating-coupled planar optical waveguides for biological sensing. Near cut-off and far from cut-off modes are investigated, and their characteristics and suitability for sensing are compared. The numeri...
