Abstract
The present disclosure relates to a monolithic waveguide substrate for enabling routing of at least one optical signal. The monolithic waveguide substrate has a monolithic engineered substrate having a uniform material composition throughout, with a first index of refraction, and with a plurality of three-dimensional waveguides each being formed fully within an interior volume thereof by a corresponding plurality of three-dimensional waveguide channels. The three-dimensional waveguide channels are formed by wall portions each having a second index of refraction different from the first index of refraction.
