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.   Miniature pulse compressor of deep-etched gratings 期刊论文 appl. optics, 2008, 卷号: 47, 期号: 32, 页码: 6058, 6063 Jia Wei; 周常河; Feng Jijun; 戴恩文 收藏  |  浏览/下载：1300/249  |  提交时间：2009/09/18 Duty cycles  Etched gratings  Femto-second lasers  Fs pulse  Groove depths  Group velocities  Inductively coupled plasma etchings  Littrow  Pulse compressors  Transmissive gratings
