Grating coupling is now currently used in evanescent-wave biochemical
sensors as a waveguide coupling element or as the sensing element. In
most coupling cases of practical interest, the Rayleigh-Fourier method
is valid, and leads to physically meaningful analytical solutions all
owing grating coupling to be designed in simple terms. In the present
paper the emphasis is placed on the grating as a waveguide coupling el
ement.
