Abstract
A dielectric substrate of a material such as silicon is used to provide controlled impedance waveguides for coupling an optoelectronic device to an electronic device. The impedance is controlled by varying the thickness of the dielectric between the signal lines and the ground plane. In the preferred embodiment, the crystallographic structure of the silicon is employed to achieve great precision of the dielectric thickness.
