Two-dimensional optical waveguides have been implanted in a compound semiconductor, zinc telluride (ZnTe), using protons and boron ions. Propagation constants of Te0 and TM0 modes have been measured for several doses of implantation, in the visible (λ=6328 Å). Losses in the range 1–3 dB/cm are observed in these first experiments, without any thermal annealing.
