Abstract
A method for photonic device includes an optical macromodule substrate including optical interconnects and a first photonic integrated circuit (PIC) including a first photonic switch, where the first PIC is mechanically coupled to the optical macromodule substrate and optically coupled to the optical interconnect. The photonic device also includes a PIC controller electrically coupled to the first PIC.
