Abstract
A photonic integrated circuit (PIC) comprises at least two optical circuits disposed on the PIC, two or more optical interfaces each configured to provide a connection to at least one external optical component, and a layout arrangement of the at least two optical circuits on the PIC, the layout arrangement configured such that the two or more optical interfaces are situated in at least one local group of optical interfaces, and the at least one local group of optical interfaces is located on at least one facet of the PIC. The at least two optical circuits may comprise a set of N single-axis 2×2 optical fiber optic gyroscope (FOG) circuits for use as a multi-axis FOG assembly in an inertial management unit (IMU) or an inertial navigation system (INS).
