1. A method for coating at least a portion of an optical waveguide with boron nitride nanotubes (BNNTs), the method comprising:
providing a solution comprising BNNTs in a liquid solvent;
contacting at least a portion of an optical waveguide with the solution so as to form a layer of the solution supported on the optical waveguide; and
at least partially removing the liquid solvent from the layer of the solution supported on the optical waveguide, thereby forming a coating of the BNNTs on a surface of the optical waveguide.
