TE/TM mode splitters on InGaAsP/InP
TL;DR: In this article, a metal cladding on one of its branches is used to separate the TE and TM polarization of the optical wave, and the polarization splitters can act in two distinct modes of operation, depending on the degree of lateral confinement of an optical rib waveguide before an asymmetric coupler.
