本工作以矢量場模型出發,對具有誘人應用前景的柱形垂直腔面發射結構( vcsel )的微腔半導體激光器( mcsl )進行了理論分析,建立了用於分析方柱形和圓柱形結構具有氧化孔徑層的激光器的模式特性的理論模型;對圓柱形結構情況進行了數值模擬,得到了振蕩波長、閾值增益隨激光器內外半徑、 bragg反射鏡層折射率、周期數以及氧化孔徑層厚度、位置和氧化物折射率的詳細變化規律;為使理論計算更接近實際,將外加金屬包殼視為非理想導體,或將金屬包殼與激光器結構隔開,分別對這兩種情況下的結果進行了討論。These research also approve some inherent phenomena in nonlinear systems such as the interleaving of stability region and instability region, the parameter sensibility of the instable modes, divergence after a relatively long time of chaotic swings ( transient chaos ), a cascade of period double bifurcations to chaos and etc. these phenomena are of great importance to both theoretical research and engineering practice
研究還證實了一些非線性系統所特有的現象,如穩定域和不穩定域的相互交錯現象,失穩模式對參數的敏感性,一段時間混沌振蕩后的無界現象(稱為預無界混池) ,由周期運動經一連串倍周期分岔直至混濁等。這些現象對理論研究與工程實踐都具有重要意義。The results show that the light field is squeezed regularly, and that the collapse - and - revival of the atomic rabi oscillation appears under the detuning. when the initial squeezed light - field factor r is weak, photon bunching alternates with photon antibunching, and the detuning leads to the reduction of photon antibunching ; to the contrary, the factor r is strong, photon statistical properties are steady bunching, and the detuning makes two - mode correlation properties steady
數值計算結果表明:光場呈現出較規則的壓縮現象;失諧量使原子rabi振蕩呈現周期性崩塌與復甦現象;當r較小時,光子的聚束效應與反聚束效應交替出現,失諧量將削弱光子的反聚束效應;當r較大時,光子呈現恆定的聚束效應,失諧量增強光場兩模非經典相關的穩定性。The states of the system and their differential signals are obtained on time by tracking differentiator, and the influence induced by nonlinear periodic load disturbance is compensated adaptively
