### Abstract

For a symmetric grating structure with a defect, we show that a fully transmitted defect mode in the band gap can be obtained as a superposition of two steady states: an amplified and an attenuated defect state. Without scanning the whole band gap by transmission calculations, this simplifies the direct calculation of the defect wavelength as the eigenvalue in a non-standard eigenvalue problem.
