Abstract :
We demonstrate mid-IR emission at a wavelength of 2.7 μm in chalcogenide glass integrated optic waveguides. Slab and rib waveguides are fabricated in RF magnetron sputtered films of erbium-doped gallium lanthanum sulfide glass. Elevated substrate temperature during deposition is found to enhance fluorescence lifetime, resulting in 2.7 μm emission from slab waveguides with a lifetime of 0.7 ms.
