Dielectric slab waveguides
Perhaps the simplest optical waveguide is the dielectric slab waveguide, also called a planar waveguide. Owing to their simplicity, slab waveguides are often used as toy models but also find application in on-chip devices like arrayed waveguide gratings and acousto-optic filters and modulators. The slab waveguide consists of three layers of materials with different dielectric constants, exte… WebDielectric Slab Waveguide. A planar dielectric slab waveguide demonstrates the principles behind any kind of dielectric waveguide such as a ridge waveguide or a step-index fiber. This model solves for the …

WebFig.1. Dielectric-loaded rectangular guide (a), the half cross section (b) In this paper, we study a slab type dielectric structure as shown in Fig.1 using a normal mode analysis. The electromagnteic properties of a planar dielectric lined waveguide had been analysed for an idealised case (w→∞) in [4] and [5]. Wakefields were calculated in [4].

We demonstrate that photonic crystal slab waveguides tailored for luminescent solar concentrator applications can …
WebIn order to capture the essence of dielectric waveguides, one can study the slab dielectric waveguide, which shares many salient features with the optical fiber. This waveguide is also used as thin-film optical waveguides (see Figure 17). We start with analyzing the TE modes in this waveguide. 164 Electromagnetic Field Theory WebA formula is developed for dielectric slab waveguides that yields general solutions of the TE eigenmode propagation constants as explicit functions of a composite independent …
