Abstract
A mirrorless optical waveguide can include a cladding and a core. The core can include an elongate section parallel to a surface plane. The core can further include two curved end sections that curve toward a surface plane. The surface plane can be parallel to a substrate. The cladding can have nanoparticles made of acrylic and/or urethane. The core can have similar nanoparticles of acrylic and/or urethane as well as nanoparticles with a high refractive index such as zirconia. The mirrorless optical waveguide can be formed by ink-jet printing.
