Abstract

We derive analytical formulations for the output phase profile of symmetrically excited one-to-N multimode interference couplers. We show that the output phase increases quadratically from the middle of the MMI waveguide, which needs to be taken into account for phase-dependent applications such as optical phased arrays.
