1. A method for forming a waveguide comprising:

  • utilizing a three-dimensional (3D) printer to deposit a plurality of layers of poly(hydridocarbyne) and poly(methylsilyne), wherein;

    the plurality of layers of poly(hydridocarbyne) are deposited in the geometry of a cladding for an optical waveguide; and

    the plurality of layers of poly(methylsilyne) are deposited so as to form the shape of a core of the optical waveguide; and

    heating the plurality of layers of poly(hydridocarbyne) and poly(methylsilyne) to a first temperature to form the optical waveguide, the optical waveguide being formed of a core of polycrystalline silicon carbide surrounded by polycrystalline diamond after the heating of the plurality of layers of poly(hydridocarbyne) and poly(methylsilyne).
