Abstract
According to some embodiments, an apparatus includes a circuit board made of polycrystalline diamond. The circuit board is formed by thermolysis of layers of a preceramic polymer. A plurality of tubes are formed within the circuit board and comprise a plurality of terminations at one or more surfaces of the circuit board. Each tube comprises a layer of graphene that is operable to permit each tube to conduct electrical current. Each layer of graphene is formed by thermolysis of the polycrystalline diamond circuit board at a temperature greater than or equal to 900 degrees Celsius. The apparatus also includes a plurality of optical waveguides formed within the circuit board. Each optical waveguide comprises a core of polycrystalline diamond surrounded by silicon carbide. The polycrystalline diamond is formed by thermolysis of poly(hydridocarbyne) and the silicon carbide is formed by thermolysis of poly(methylsilyne).
