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-450-340 IMU provides the safe, accurate performance autonomous platforms demand.

PIC Inside









State-of-the-art Electronics
EMCORE’s Dual Core DSP electronics with ARM processor requires less power for extended product life and offers higher speed with integrated multi-channel processing. Low-loss optical circuits use less light for greater efficiency.
