Abstract
A light transmitting structure or optical waveguide (47) of the present invention can provide both optical and electrical conductivity. The optical waveguide (47) is capable of simultaneously transmitting multiple optical and electrical signals. The optical waveguide (47) has several cladding layers (40, 41, 42, 43, 44) which optically isolate several different regions of waveguide core material (45, 46) through which the multiple optical signals are transmitted. To provide a compact structure, portions of the cladding layers (42, 43, 44) of the optical waveguide (47) are used as electrical conductors while the waveguide core material (45, 46) is used as an electrical insulator for the electrical conductors.
