Highly Sensitive Detection of Olive Oil Using Plasmonic Photonic Crystal Fiber
摘要
Today, corruption of olive oil samples (OOSs) is a serious and healthy concern in all the world, and as a result, an efficient as well as accurate testing tool of the OOSs corruption is crucial. Here, a novel PCFS is projected to test OOSs quality which involves an easy array of rectangular holes in the cladding zone and the core is treated as a square gap. The full-vector finite element approach (FEA) is employed with the help of COMSOL Multiphysics software. The suggested PCFS achieved an ultra-high relative sensitivity (RSE) of 99.48% at 2.5 THz. Furthermore, the loss in the projected PCFS is very tiny which proves the effectiveness of the planned PCFS. Also, this PCFS has a tunable design and simple structure; it can be fabricated easily using the prevailing fabrication schemes. As a result, the suggested PCFS will act as a key role in chemical and bio-testing in diverse areas swiftly.
