Abstract

This paper describes the measurement of optical phase shift of polarized light in the optical devices using Mach-Zehnder interferometer (MZI). The case of one light source traveling into the interfermerter, with one modulated path using the optical devices such as single mode fiber, polarization maintaining fiber, nonlinear sammarian fiber, erbium dope fiber and LiNbO3 (lithium niobate) are investigated. The behavior of signal outputs obtained of each case is detected and plotted, then discussed the use of such a device for phase shifter or switching. The optical output signal characteristic of the detected signal can be analyzed for the potential of using in the case of device modeling and design, either for optical sensor or communication application. Preliminary results have shown that the one using polarization maintaining fiber showing the phase shifter characteristics.
