THE CALCULATION OF EFFECTIVE REFRACTIVE INDEX BY USING DISPERSION PROPERTY IN PHOTONIC CRYSTAL WITH ONE DIMENSION

Abstract

In this paper, the forbidden band structure in which able to propagate certain frequencies and transmission properties with respect to periodicity condition are investigated in one dimension photonic crystal has a dielectric constant which change periodic. However, the dispersion properties with respect to refractive indexes belong to certain crystal are used in calculation of n_eff refractive indexes of guided modes.

TEK BOYUTLU FOTONİK KRİSTALDE DAĞILIM ÖZELLİĞİNDEN YARARLANARAK ETKİN KIRILMA İNDİSİNİN HESAPLANMASI

Abstract

Bu çalışmada, dielektrik sabiti periyodik olarak değişen tek boyutlu bir fotonik kristalde belli frekansların iletimine izin veren yasaklı band yapısı ve periyodiklik koşuluna bağlı olarak iletim özellikleri incelenmiştir. Ayrıca, belirlenen kristale ait kırılma indislerine bağlı olarak incelenen dağılım özellikleri, kılavuzlanan modların n_eff etkin indislerinin hesaplanmasında kullanılmıştır.
