摘　　要：Based on the guided mode resonance effect,single-layer transmission filters are presented.It is found that there is an intersection region in which the strong modulation waveguide modes TE_(0) and TE_(2) can be simultaneously excited by the second and first diffraction orders,respectively.A very high transmission peak emerges when the leaky modes interact with each other.Based on the normalized eigen-function of a single-layer waveguide grating,the high resonance transmission filters can be designed at any central wavelength.In order to demonstrate this concept,we design narrow line-shaped band pass filters with a central wavelength at 0.8,1.06 and 10.6μm.
