1Improvement of Amplitude-Shift-Keying Signal Quality by Employing an Effective Spectrum Equalization Method in a Combined FSK/ASK Modulation Scheme显示文摘A simple, economical and applicable spectrum equalization method is implemented by employing a reshaping filter in the combined frequency-shift-keying/amplitude-shift-keying modulation scheme to improve the quality of amplitude-shift-keying optical signal. The 3-dB improvement for eye diagram height is experimentally demonstrated.忻向军 P.S.André A.L.J.Teixeira 徐重秀 AnaFerreira TiagoSilveira P.M.Monteiro F.daRocha J.L.Pinto 2005Chinese Physics Letters2005,22,8:8
2Demodulating the Response of Optical Fibre Long-Period Gratings: Genetic Algorithm Approach显示文摘长时期栅栏从的物理参数的抽取光谱反应不是容易的进程。我们在场综合的一种解调技术一个长时期栅栏的物理参数在一根光纤记录了。解调通过一个基因算法的实现被完成。提取参数与为长时期栅栏知道的典型价值一致。P. S.

3Impact of nitrogen doping on growth and hydrogen impurity incorporation of thick nanocrystalline diamond films显示文摘A much larger amount of bonded hydrogen was found in thick nanocrystalline diamond(NCD) films produced by only adding 0.24% N2 into 4% CH4 /H2 plasma,as compared to the high quality transparent microcrystalline diamond(MCD) films,grown using the same growth parameters except for nitrogen.These experimental results clearly evidence that defect formation and impurity incorporation(for example,N and H) impeding diamond grain growth is the main formation mechanism of NCD upon nitrogen doping and strongly support the model proposed in the literature that nitrogen competes with CH x(x=1,2,3) growth species for adsorption sites.顾利萍 唐春玖 江学范 J.L.Pinto 2011Chinese Physics B2011,20,5:0
