Abstract
An apparatus with integrated optical waveguides. The apparatus has: a plurality of layers, wherein a conductive pathway is patterned on a surface of at least one of the plurality of layers. The plurality of layers are laminated together. A plurality of nanocomposite-inks, each with a nanofiller dispersed in an organic matrix have optical dispersion different from the other plurality of nanocomposite-ink, form the optical waveguides. The optical waveguides are formed on the surface of, or within, at least one of the plurality of layers.
