摘要: 本文提出了分析包含非線性介質(zhì)的層狀介質(zhì)波導(dǎo)特性的等效傳輸線方法。通過(guò)把線性和非線性介質(zhì)分別用等效傳輸線表示,從而把非線性介質(zhì)這一復(fù)雜的電磁場(chǎng)問(wèn)題等價(jià)成一個(gè)電路問(wèn)題求解。其本征方程可以利用橫向諧振原理得到。本文最后分析了層狀介質(zhì)波導(dǎo)包含飽和和非飽和非線性介質(zhì)時(shí)TE模的傳播功率與歸一化傳播常數(shù)之間的關(guān)系。所獲得的結(jié)果與有關(guān)文獻(xiàn)符合得相當(dāng)好。

Abstract: This paper presents a so called equivalent transmission line method for the analysis of multilayer dielectric waveguide involving nonlinear dielectric. By introducing the equivalent transmission line model of nonlinear dielectric and linear dielectric, the electromagnetic field problem about the nonlinear dielectric waveguide can be equivalent to a circuit problem. The eigen-equation governing the nonlinear dielectric waveguide can be obtained by using the transversal resonance technique. Finally, the multilayer dielectric waveguides involving saturable or non-saturable nonlinear dielectric are simulated, and the relations between the propagating power of TE mode and the normalized wavenumber are given. The results obtained are in good agreement with that in the references. -
