Abstract
A photo-electric integrated circuit device comprises an on-die optical input/output device. The on-die optical input/output device comprises a substrate having a trench, a lower cladding layer disposed in the trench and having an upper surface lower than an upper surface of the substrate, and a core disposed on the lower cladding layer at a distance from sidewalls of the trench and having an upper surface at substantially the same level as the upper surface of the substrate.
