Here, in this paper we have discussed the polarized optical wave and modes aiming to maintain state of polarization. An optical wave being composed of two orthogonal electromagnetic field components varying with amplitude and frequency. A polarized light occurs when these two components differ in phase or amplitude. Polarization in optical fiber (polarization maintaining optical-fibers : maintaining low PMD) has been extensively studied and methods are available to minimize the phenomenon. Lower the PMD higher will be the information carrying capacity of the optical fiber, hence low PMD should be maintained". Here, basic principles and technical background are introduced in explaining how the polarization in fiber optics works.
