In this study, some design parameters such as normalized frequency and especially normalized propagation constant have been obtained, depending on some parameters which are functions of energy eigenvalues of the carriers such as electrons and holes confined in a single step-index waveguide laser (SSIWGL) or single stepindex waveguide (SSIWG). Some optical expressions about the optical power and probability quantities for the active region and cladding layers of the SSIWG or SSIWGL have been investigated. Investigations have been undertaken in terms of these parameters and also individually the optical even and odd electric field waves with the lowest-modes were theoretically computed. Especially absorption coefficients and loss coefficients addition to some important quantities of the single step-index waveguide lasers for the even and odd electric field waves are evaluated.

Bu çalısmada, adım kırılma indisli tekli dalga kılavuzlu lazerde veya adım kırılma indisli tekli dalga kılavuzunda hapsedilmis elektron ve delik gibi tasıyıcılara ait enerji özdegerlerinin fonksiyonları olan bazı parametrelere baglı normalize frekans ve özellikle normalize yayılım sabiti gibi tasarım parametreleri elde edilmistir. Adım kırılma indisli tekli dalga kılavuzunun veya adım kırılma indisli tekli dalga kılavuzlu lazerin aktif ve gömlek bölgeleri için optik güç ve olasılık nicelikleri ile ilgili bazı optik ifadeler, bu parametreler cinsinden incelenmistir. Arastırmalar bu parametreler cinsinden yapılmıstır ve de teorik olarak en düsük çift ve tek modlu optik elektrik alan dalgaları için ayrı ayrı hesaplanmıstır. Çift ve tek elektrik alan dalgaları için, adım kırılma indisli tekli dalga kılavuzlu lazerlerde bazı önemli büyüklüklere ilave olarak özellikle sogurma ve kayıp katsayıları degerlendirilmistir.
