| 1 | GLOBAL CONVERGENCE PROPERTIES OF THREE-TERM CONJUGATE GRADIENT METHOD WITH NEW-TYPE LINE SEARCH显示文摘Abstract. In this paper, a new Wolfe-type line search and a new Armijo-type line search are proposed, and some global convergence properties of a three-term conjugate gradient method with the two line searches are proved. | WANGChangyu DUShouqiang CHENYuanyuan | 2004 | Journal of Systems Science & Complexity2004，17，3： | 13 |
| 2 | Research progresses of SOI optical waveguide devices and integrated optical switch matrix显示文摘SOI (silicon-on-insulator) is a new material with a lot of important perform- ances such as large index difference, low transmission loss. Fabrication processes for SOI based optoelectronic devices are compatible with conventional IC processes. Having the potential of OEIC monolithic integration, SOI based optoelectronic devices have shown many good characteristics and become more and more attractive recently. In this paper, the recent progresses of SOI waveguide devices in our research group are presented. By highly effective numerical simulation, the single mode conditions for SOI rib waveguides with rectangular and trapezoidal cross-section were accurately investigated. Using both chemical anisotropic wet etching and plasma dry etching techniques, SOI single mode rib waveguide, MMI coupler, VOA (variable optical attenuator), 2×2 thermal-optical switch were successfully designed and fabricated. Based on these, 4×4 and 8×8 SOI optical waveguide integrated switch matrixes are demonstrated for the first time. | YUJinzhong CHENShaowu XIAJinsong WANGZhangtao FANZhongchao LIYanping LIUJingwei YANGDi CHENYuanyuan | 2005 | Science in China(Series F)2005，48，2： | 4 |
