We present a new simulation technique for Distributed Feedback lasers in 2D. The method is based on recently developed Trigonometric Finite Wave Elements (TFWEs) that approximate oscillating and internally reflected optical waves. Since our method is derived from the Transfer Matrix Method (TMM), the TFWE method provides exactly the same results as the TMM for 1D problems but it can be extended to higher dimensions and to time-dynamic simulations. Therefore, large laser structures and the influence of the injected current can be simulated time-dynamically. Furthermore, the wavelengths of the competing modes can be detected using the Fast Fourier Transformation.
