Cadmium telluride: a silicon-compatible optical material as an alternative technology for building all-optical photonic devices

In this work, we report theoretical and experimental results on the use of Cadmium Telluride (CdTe) doped with Zinc (Zn) as core material for the development of all-optical photonic devices. We include the design of optical waveguides for strong field confinement, technological processes to grow CdTe on 6" or 8" wafers (suitable for high-volume manufacturing) as well as the fabrication and optical characterization of optical waveguides with a CdTe core.
