Surface Plasmon Resonance‐Based Fiber and Planar Waveguide Sensors

Abstract

Bulk surface Plasmons resonance devices have been researched for several decades. These devices have found a special niche as high-sensitivity refractive index sensor in biomedical applications. Recent advances in guided wave devices are rapidly changing the capabilities of such sensors, not only increasing convenience of use but also opening opportunities due to their versatility. This paper reviews many of these devices and presents some of their salient features.

Analysis of a metal clad waveguide sensor having metamaterial as a guiding layer

“…Hence, the adlayer sensitivity (change in resonance angle/change in the thickness of adlayer) is larger for the proposed waveguide sensor rather than metal clad waveguide sensor [9] as shown in Table 6. Apart from this, resolution of the sensor is an important parameter which is defined as the minimum change in the parameter to be determined, which can be differentiated by sensor [21].…”

Gas sensing demonstration by using silica high-mesa waveguide with amplified cavity ring down spectroscopy technique

“…In order to solve this problem, we have proposed a silica high-mesa waveguide [5] for the gas-cell (breath detection part). The gas-sensing utilizing waveguide have been studied by many research institutes [6,7,8,9,10,11]. Similarly, in measuring method exploiting waveguide, a wide variety of method is also studied such as infrared absorption [6,7,8], Raman scattering [9], surface plasmon [10], and polymer colorimetric analysis [11].…”

Optical waveguide biosensor based on modal interference between surface plasmon modes

“…[1][2][3][4][5]. Amongst these, optical waveguide based SPR sensors have extra advantage of their possible integration with other optical components on a single chip [6,7].…”
