The present disclosure relates to polarization rotator-splitters that include oxide claddings. One example embodiment includes a device. The device includes a first waveguide. The first waveguide includes a first end configured to receive electromagnetic waves having a first polarization with a first mode-order and electromagnetic waves having a second polarization. The first waveguide also includes a mode-conversion section configured to convert electromagnetic waves having the second polarization into electromagnetic waves having the first polarization with a second mode-order. Additionally, the device includes a second waveguide. The second waveguide also includes a coupling section configured such that electromagnetic waves having the first polarization with the second mode-order are converted into electromagnetic waves having the first polarization with the first mode-order and coupled from the coupling section of the first waveguide into the coupling section of the second waveguide.
