Numerical simulation results show that for given device structure with wavelength of 1.55 m  the feedback coupling coefficient and the surface radiation coupling coefficient of the second-order grating have great influence on the emission characteristics of the device. By choosing different duty cycles of the grating  we can change the two coupling coefficients  which affect the emission characteristics. For an overall consideration  an optimal duty cycle of 0.43 is chosen. The optimized results show that the device works without degeneracy modes and spatial burning hole. Besides  the side-mode suppress ratio (SMSR) and external differential quantum efficiency reach as high as 42 dB and 47%  respectively. 2010 SPIE.   Grating optimization and experiment on high-power distributed feedback lasers 期刊论文  iSwitch采集 Acta physica sinica, 2007, 卷号: 56, 期号: 3, 页码: 1613-1616 作者:  Fu Sheng-Hui;  Song Guo-Feng;  Chen Liang-Hui 收藏  |  浏览/下载：28/0  |  提交时间：2019/05/12 Dfb lasers  Coupled-wave theory  Second-order gratings  Sidemode suppression ratio   Effect of metal contact's reflection on the effective coupling coefficient of second-order dfb laser diodes 期刊论文  iSwitch采集 Microwave and optical technology letters, 2004, 卷号: 42, 期号: 4, 页码: 339-342 作者:  Zhong, Y;  Zhu, XP;  Song, GF;  Huang, YD;  Chen, LH 收藏  |  浏览/下载：24/0  |  提交时间：2019/05/12 Dfb lasers  Second-order gratings  Coupled-wave equations  Effective coupling coefficient
