| 2 | Investigation of Induced Distortions in a-Si∶H/a-SiN_x∶H Multilayers by Raman Scattering Technique显示文摘The a Si∶H/SiN x ∶H sample series are investigated by means of Raman scattering technique(RST).

| 11 | Evolution of Electron Phase Orbits Based on Multi-photon Nonlinear Compton Scattering显示文摘The electron movement based on the multi-photon nonlinear Compton scattering with the extra-intense stationary laser field is discussed by using KMR (Kroll-Morton-Rosenbluth) theory.We find that there exists only an evolution from periodicity to non-periodicity of the un-captured electron phase orbits after the energy exchange between the electron beam and laser fields.With the increase of the absorbed photon number n by an electron, this evolution will be more and more faster, while it is rapidly decreased with the enhancement of the collision non-flexibility ξ of the electrons and photons; When the electrons are captured by the laser fields, the evolution is finished, the electrons will stably transport,and the photons dont give up the energy to these electrons. | HAO Dong-shan, HAO Xiao-fei (Dept.of Phys.,Zhumadian Teachers College, Zhumadian 463000,CHN) | 2003 | Semiconductor Photonics and Technology2003，9，3： | 5 |

| 13 | A Breather in Birefringent Fibers显示文摘The propagation properties of the breather in birefringent fibers are investigated. The breather can propagate stably in strongly birefringent fibers. The propagation law can be expected. However, random birefringence makes the propagation of the breather more complex. The breather will partly disappear and partly appear, even may split into two smaller breathers. In addition, the varying range of relative time displacement between two components of the breather becomes narrower with the effect of third-order dispersion. If third order dispersion is too strong, the breather behavior will disappear gradually during the transmission. The breather can exist in random birefringent fiber with dispersion management rather than in strongly birefringent fiber. | CHEN Wei cheng 1,2 , XU Wen cheng 1 (1.Dept. of Phys., Foshan University, Foshan 528000, CHN 2.Inst. of Quantum Electron., South China Normal University, Guangzhou 510631, CHN) | 2002 | Semiconductor Photonics and Technology2002，8，4： | 4 |

Its signal processing ability will decide whole system’s performance to some extent because it will affect directly the factors such as resolving power, precision and dynamic range. The signal processing is usually realized by analog circuits which was more inferior in stability, flexibility and anti-jamming to digital processing system. A digital processing system of optical fiber acceleration seismometer has been designed based on the embedded system design scheme. Synthetic-heterodyne demodulation has been studied, and signal processing has been realized. The double processors of ARM and DSP are employed to implement respectively the system control and signal processing, and to provide the output interfaces such as LCD, DAC and Ethernet interface. This system can vary with the measured signal in real time and linearly, and its work frequency bandwidth is between 10Hz and 1kHz. The system has better anti-jamming ability and can work normally when the SNR is 40dB. | MENG Ju WANG Jin-hai CHEN Cai-he ZHANG Cheng | 2006 | Semiconductor Photonics and Technology2006，12，3： | 4 |
