Project Description

Compact Ultrasensitive Erbium-doped Waveguide Optical Gyros, Phase I
In this program, we propose to develop a new photonic-integration platform that incorporates optical gain in resonant waveguide optical gyroscopes. This new photonic integration platform is based on our existing low-loss SiN/SiO2 PLC photonic integration technology and incorporates a doped Aluminum Oxide layer for gain. One key resonant waveguide optical gyro design constraint is the relationship between the waveguide length, which can increase the Sagnac effect, and waveguide loss, which decreases the gyro resolution. Freedom Photonics' low loss SiN PLC platform is clearly an adequate path forward for record-breaking Gyro performance. With introduction of gain into the PLC, new possibilities arise for enhanced sensitivity, simplified control electronics, and ultra compact and robust designs. More »
