| Abstract: | This paper reports on a novel design of a remote sensor for temperature detection based on surface plasmon resonance and optical fiber technology. We theoretically analyze the performance of proposed sensor under different conditions related to its constituents, i.e., optical fiber, metallic layer, sensing region, and launched light. The effect of the related parameters such as numerical aperture, fiber length, core diameter, FWHM of the Gaussian input on sensor is analyzed along with its physical explanation. The numerical results presented in this paper leads to a significant optimization of the important design parameters to achieve a high temperature detection accuracy and sensitivity of a fiber optic remote sensor. |
