Researchers at the Karlsruhe Institute of Technology (KIT) have for the first time used polycrystalline diamond to manufacture optical circuits, as the material has the particular optical and mechanical properties necessary for this.
“Diamond has several properties that allow us to manufacture all components of a ready-to-use optomechanical circuit monolithically, so to speak,” says KIT research group leader Wolfram Pernice. The elements manufactured in this way include resonators, circuits, and the wafer, and are attractive because of their high quality, he said. The scientists have published their results online in Nature Communications (DOI: 10.1038/ncomms2710).
