        摘要：The electromagnetic field is quantized, the envelope soliton is discribed by the density matrix. The Fokker-Planck equation of P representation is drawn from master equation in quantum optics. The quasiclassical nonlinear Schrodinger eguation is introduced for soliton envelope in an optical fiber. The application of the equation is discussed.  
        关键词：soliton propagation;Quantum field theory;The effect of collapes and revival

        摘要：In ITU-T G. 650,definition of mode-field diameter is given based on farfield scan measurment,whereas definition of mode-field diameter by far-field scan conform with daily common used Petermann’s definition substantially. In this paper,conformability of defining mode-field diameter by far-field scan and variable aperture with Petermann’s definition is derived from theorem.

        摘要：The model of EDFA that has been made is modified by considering the base loss of erbium-doped fiber and ASE. The rate equations and propagation equations that have been modified are given. The distributions of signal and pump power with fiber length and the EDFA gain characteristic and output power saturation have been calculated by computer.Th3e results are in accord with our experimental results very well.

        摘要：In this paper,the interference fringes of X-ray diffraction rocking curves from MOCVD epitaxial chips are discussed. They show the accuracy of measured thickness using the interference fringes method. The various characteristics of the interference fringes are also discussed in order to get some structure knowledges from the epitaxial chips by human eyes. It will be convenient to discriminate and use correctly the interference fringes.

        摘要：用锥形光纤改进孤子传输光纤放大器的发展，打开了通往长距离全光通信的大门。未来的高速光通信系统很可能要利用光孤子——一种沿光纤传播而几乎不变形的脉冲。但对孤子通信来说也有一个限制性因素，即孤子长距离传输后发生的能量损耗。随着脉冲能量的下降，非线性光学效...
