Weak modulated dielectric grating can be equivalent to planar waveguide. When it diffracted high-order spatial sub-wave is coupled with waveguide mode, a guided mode resonance is formed.
弱调制介质光栅可等效为平板波导，经其衍射的高级次子波与波导模式耦合时，形成导模共振。
This article gives the elementary analysis on why does high-order mode resonance arise and how to control it, and proposes several practical methods controlling high-order mode excitation.
