The guided-mode resonance phenomenon in curved grating structures was studied. By using finite-difference timedomain simulation in the cylindrical coordinate system, we investigated the dependence of the peak reflectivity and bandwidth of the resonance upon the curvature radius. We clarified that the reflectivity and bandwidth were similar to those of flat grating structures for a finite range of curvature. We also discussed the key factor that determines the performance of reflection.
