Abstract
An encapsulated package is provided that includes a pair integrated circuit (IC) die. A radio frequency (RF) circuit on one of the IC die is operable to transmit an RF signal having a selected frequency. An RF circuit on the other IC die is operable to receive the RF signal Encapsulation material encapsulates the IC die. A photonic waveguide couples between the RF transmitter and RF receiver to form galvanic path isolation between the two IC die. The photonic waveguide is formed by a photonic structure within the encapsulation material.
