We report near-infrared (IR) to mid-IR (up to 3.4 μm wavelength) multimode waveguiding in deep buried channel waveguides fabricated inside rare-earth ion-doped ceramic YAG for the first time to our knowledge. Waveguide laser operation at around 2 μm wavelength with multi- or single-transverse modes is also preliminarily demonstrated from these waveguides.
