Abstract

Bu çalışmada bir asimetrik dilim dalga kılavuzunun etkin kırılma indisini tespit etmek

için hem analitik yöntem hem de bir yaklaşım yöntemi olan sonlu farklar yöntemi kullanılmıştır.

Dalga kılavuzunda diyot lazerin etkin yayılımının sağlanması için etkin indis değeri

hesaplanmıştır. Analitik yöntemle elde edilen sonuçla sonlu farklar yöntemi ile elde edilen

sonuçların kullanılacak kılavuz türü için geçerliliği karşılaştırılmıştır.

Keywords

Optik dilim dalga kılavuzu, analitik yöntem, sonlu farklar yöntemi, etkin kırılma indisi, elektromanyetik dalga

Theoretical Calculation Of Effective Refractive Index Of An Asymmetrical Dielectric Slab Waveguide

Abstract

In this paper, we use both analytical method and finite difference method to determine effective refractive index of an asymmetrical slab waveguide. Effective index value is

calculated to efficient propagation of diod laser in slab waveguide. The validity of the obtained

values by both of methods are compared for using waveguide type.

Keywords

Optical slab waveguide, analytical method, finite difference method, effective refractive index, electromagnetic wave.
