Abstract

Augmented low index waveguides consist of a dual core waveguide layer where the transverse electric (TE) mode is confined to the high index region and the transverse magnetic (TM) mode is confined to the lower index core. The result is a large difference in propagation constants between the TE and TM modes which has applications for on-chip polarization manipulation. In this paper we will demonstrate how this concept can be used to realize polarization rotation, polarization beam splitters and polarizers in the silicon photonics platform.
