Abstract:
The present invention relates to optically transparent polymer nanocomposite solid substrates with surface relief features which facilitate joining and adhering multiple materials to the solid substrate, and to methods for their manufacture. The nanocomposite material comprises a host matrix (10) with nanoparticles (11). In one embodiment the surface relief features are pedestals. The material is formed by coating nanoparticles (11) with a halogenated outer layer (12) and dispersing the coated nanoparticles into a host matrix material (10). The coating material inhibits agglomeration. Such substrates are used for optical waveguides with a core formed of the nanocomposite material and surface relief features on the waveguide. The scattering loss due to the size and distribution of nanoparticles and nanopores is addressed. In some embodiments the host matrix is a halogenated polymer.
