An apparatus and methods for optical switching using nanoscale optics are disclosed herein. One or more signal conduits are coupled to a lead frame that is subsequently embedded in an encapsulated semiconductor device package. The operating modes of the multimode circuit may be dynamically selectable. A BST layer is formed on the single crystal oxide layer. The acknowledgement may further include one or more of a time reference used by the system; and an identification of secondary technologies used by the system.
