Equivalent network analysis of optical strip waveguides

광 스트립 도파로의 등가회로망 해석

Taking the normal mode transmission direction perpendicular to the substrate, an alternative equivalent network formulation is developed for the analysis of optical strip waveguides. All kinds of mode couplings between the normal modes are included in this formulation. Compared to the previous equivalent network formulations, the calculations are simplified especially when the thickness of the uniform slab is thin enough such that no well guided modes are available along the uniform slab waveguide.
