Technology Details

Photonic Integrated Chip Technology
EMCORE’s photonic integrated chip (PIC) technology reimagines FOG technology by replacing individual fiber components with an innovative integrated planar optic chip. This results in a FOG with PIC Inside™ that’s reliable and robust. With three of these integrated photonic gyros at its core, the TAC-450-320 IMU provides the safe, accurate performance autonomous platforms demand.
