| 摘 要： | 建立了周期结构的非线性介质在准相位匹配条件下进行和频波长变换的数学模型.以AlGaAs为例,利用该模型数值模拟了波导传输损耗、波导长度和变换效率的关系以及泵浦功率和和频功率间的关系. 结果显示,泵浦光功率、传输损耗和器件长度是影响变换信号的主要因素.

| Abstract: | A theoretical model of wavelength conversion based on Sum-Frequency Generation Quasiphase-Matched in nonlinear medium with periodically structure is established. For example, AlGaAs, using this model, the simulation of the numerical value relationship of device length and conversion efficiency for different transmission loss is given, as well as the relationship of pump power and conversion wavelength power. Results show that pump power, transmission loss and device length are main factors in the process of conversion. |
