Abstract
Optical waveguides for use in planar structures, such as dielectric layers in multichip modules exhibit low optical loss. The optical waveguides are provided by methods that involve doping of the dielectric layers. The waveguides can be used to interconnect electronic elements and transmit signals at speeds that are compatible with high speed electronic elements.
