We propose a method for analyzing the diffraction of beams with finite cross-section by a waveguide grating. In this method a beam is expanded into a series of plane waves utilizing the Fourier transform. For each plane wave the amplitude reflectance

Thin-film organic distributed feedback (DFB) lasers processed with elastomeric polymers allow fabrication of flexible and continuously tunable coherent light sources. So far, the realized laser devices fall short on broad continuous tuning range. We
