基片集成波導的基本概念是利用基片的上下金屬板和兩排間隔一定距離的金屬孔構成波導的金屬壁,由於每排金屬孔孔間距遠小於波長,因此由縫隙泄漏的能量很小,這相當于內部填充了介質的矩形波導,所以能夠用矩形普通波導實現的結構也都可以用基片集成波導來實現,比如功分器、濾波器、天線、耦合器、振蕩器等。It has been shown that : the little indentation which represents the quantum noise of the system appears in the evolution curves ; the quantum noise which is caused by virtual photon field gradually becomes weak when w increases, the quantum noise increases when n increases ; the virtual photon process make the antibunching effect strengthen, make the squeezing degree deepen obviously, and lead to the additional vibration of entropy, the oscillation extent of the additional vibration of entropy increases when n increases and decreases when co or g increase. besides, the quantum dynamics of two coupling atoms interacting with a single mode ligh t field in a kerr medium is studied in this paper ; the influences of the kerr effect on the mean photon number, the degree of second order coherence of field, the evolution of the field entropy and the squeezing effect are also discussed
)的增大,量子噪聲分別減小和增大;虛光子過程使光場的反聚束效應增強,使光場的壓縮程度明顯加深,並引起了附加的「熵振蕩」 ,這種附加「熵振蕩」的幅度將隨著光場初始平均光子數( ? )的增加而增大,隨著光場頻率和原子間耦合系數g的增大而減小。本文還研究了充滿kerr介質腔中「耦合雙原子-單模光場」相互作用系統的量子動力學性質,研究了克爾效應對場的平均光子數、二階相干度、場熵演化特性及光場壓縮效應的影響。Abstract : we have studied the spontaneous emission from a three - level atom with an external - driving field in a photonic crystal. as a result of quantum interference and photon localization, the population in the two upper levels displays quasi - oscillatory oroscillatory behavior. this depends on the initial atomic state and the relative positions of the two upper levels from the forbidden gap. the intensity and the phase of the external field can affect spontaneous emission from the atom. the properties are different from a three - level atom either in vacuum or in aphotonic crystal without an external driving field
文摘:討論了在雙光子驅動場作用下,三能級原子在光子晶體中的自發發射問題.由於量子干涉和光的局域化作用,兩個上能級中的占據數將具有周期振蕩或準周期振蕩的性質,這不僅依賴于兩個上能級與禁帶的相對位置,同時也依賴于原子的初始狀態,而且還與驅動場的強度、驅動場的入射位相有關.這些性質既與真空中帶有驅動場的原子的自發發射性質不同,也有別于無驅動場作用下光子晶體中三能級原子的自發發射性質The system parameters are developed at the same time, and some universal conclusions on the theoretical analysis of pll are reached. then, we have carried on analysis and research to the theory of differential delay ring voltage controlled oscillator ( vco ). on this basis, a improved differential delay ring vco with more efficient loads is described. this circuit has been designed and implemented in 0. 35 m cmos technology
