This method is based on the characteristics of MTF and demonstrates that when the characteristic triangle is equilateral with each side 3th power of sub-MTF cutoff frequency  MTF has no zero value below cutoff frequency  thus we can obtain the minimum fill factor. Furthermore  we apply it to some typical sparse arrays  such as Golay3  Golay6  Ring6 and Tri-arm7  and get their fill factors of 33.33%  15.16%  30.11%  and 11.14% correspondingly  which are consistent with numerical results. 2011 IEEE.   Phase-locked ring-defect photonic crystal vertical-cavity surface-emitting laser 期刊论文  OAI收割 applied physics letters, 2010, 卷号: 96, 期号: 15, 页码: art. no. 151103 Liu AJ (Liu Anjin); Chen W (Chen Wei); Xing MX (Xing Mingxin); Zhou WJ (Zhou Wenjun); Qu HW (Qu Hongwei); Zheng WH (Zheng Wanhua) 收藏  |  浏览/下载：224/33  |  提交时间：2010/05/04 coupled mode analysis  laser mode locking  laser modes  photonic crystals  ring lasers  surface emitting lasers  SEMICONDUCTOR-LASERS  ARRAYS  VCSEL  EMISSION   Magnetic field induced phase branches of the superconducting transition in one-dimensional pi-loop arrays 期刊论文  OAI收割 SUPERCONDUCTOR SCIENCE & TECHNOLOGY, 2005, 卷号: 18, 期号: 11, 页码: 1539 Liu, DT; Zhu, XM; Tian, Y; Zhao, SP; Chen, GH 收藏  |  浏览/下载：16/0  |  提交时间：2013/09/18 QUANTUM SUPERPOSITION  PAIRING SYMMETRY  RING ARRAYS  STATES
