Abstract
PLC architectures and fabrication techniques for providing electrical and photonic integration of a photonic components with a semiconductor substrate. In the exemplary embodiment, the PLC is to accommodate optical input and/or output (I/O) as well as electrically couple to a microelectronic chip. One or more photonic chip or optical fiber terminal may be coupled to an optical I/O of the PLC. In embodiments the PLC includes a light modulator, photodetector and coupling regions supporting the optical I/O. Spin-on electro-optic polymer (EOP) may be utilized for the modulator while a photodefinable material is employed for a mode expander in the coupling region.
