Abstract

We present the details and characteristics of graded index multimode mode interference (GIMMI) and its applications in optical communication components. This structure has unique features that allow for less sensitive wavelength dependant than the step Index case. This feature allows for wideband applications. In this paper, we present the applications of this structure to design wideband ultrafast integrated optical switch and integrated wideband polarization splitter. The graded index effect is produced using stair case index profile that mimics the parabolic index profile. The MMI with parabolic index profile has the analytical expression for the imaging length which provides simple design equations for the whole structure. The accuracy of this model is verified using 3D full vectorial beam propagation method.
