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.
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.
