Abstract

In this paper we theoretically realize the all optical pressure sensor using the Mach-Zehnder interferometer (MZI). In this model, one arm of MZI is plated with silver and surrounded with specially design polymer filled metal cylinder with opening at one side where pressure applied. The MZI structure can be effectively used to sense surface plasmon resonance and used as an efficient pressure sensor. The paper includes the suitable expressions for the optimizing the power entering each branch of the Mach-Zehnder interferometer, the SPR phase and amplitude changes. The results are very effectively supported by the use of COMSOL and MATLAB.
