FAZ TESPİTİNE DAYALI YÜZEY PLAZMON RESONANS TABANLI ALGILAMANIN KIZILÖTESİ BANTTA ANALİZİ

Öz

Yüzey Plazmon Rezonansı (YPR) tabanlı algılamada geleneksel olarak kullanılan ışık şiddeti tespiti yerine faz tespitine dayanan bir yöntemin kullanılmasının önemli avantajları vardır. Bununla beraber ışık spektrumunun görünür aralığının yerine silikon kullanımıyla kızılötesi aralığında YPR tabanlı algılama yapılması da bazı umut verici avantajlara sahiptir. Bu çalışmada, faz algılamaya dayalı SPR algılamanın kızılötesi aralıkta ışık kullanımıyla birleştirilmesinin yaratacağı performans artışları matematiksel bir model ve sayısal benzetim yöntemleri kullanılarak incelenmiştir. Elde edilen sonuçlar, görünür banttaki benzetimlerden elde edilen sonuçlarla karşılaştırılmış ve kızılötesi bantta faz ölçümü tabanlı yaklaşımın daha yüksek performans verdiği gösterilmiştir.

Analysis of Surface Plasmon Resonance Sensing Based on Phase-Detection in the Infrared Range

Öz

Using phase detection in Surface Plasmon Resonance (SPR) sensing has potential improvements to the conventional intensity detection based SPR. Other than the phase detection and intensity detection based SPR in the visible range of the spectrum, employing SPR sensing principles in the infrared range by the use of silicon has also some promising advantages. Combining these two, in this paper, phase detection-based SPR sensing in the infrared range is studied using a mathematical model and numerical simulations. The results are compared with the results obtained by the simulations in the visible range. Performance improvements are noted by the use phase detection in the infrared range.
