Design and Analysis of the DFB Laser Based on n-ZnO/p-AlGaN LED
摘要
Abstract
According to the rigorous coupled-wave theory and medium slab waveguide theory,the structure of Distributed Feed Back (DFB)semiconductor laser based on single-crystal n-ZnO/p-AlGaN Light Emitting Diode (LED)structure is simulated and designed by the Comsol Multiphysic software.The distribution of a two-dimensional electric mode is analyzed with near-ul-traviolet light emission at the applied voltage of 4 V on the n-ZnO/p-AlGaN LED structure.The variation of the single longitu-dinal mode with different parameters of the grating is obtained.Also,the simulation results show that the electric field mode reached 5.877 4×107 V/m with narrow spectral linewidth and preferable mode selectivity under the condition of the duty ratio of 50%,grating period of 109.2 nm and the grating height of 69.8 nm.The results in the paper provide a foundation for the design and processing of electrically pumped DFB semiconductor laser.关键词
