Summary

Description

We propose a new approach for to the design and fabrication of miniaturized Interferometric Fiber Optical Gyroscope (FOG) that enables the production of smaller IRU with enhanced performance. The size and performance limitations of the standard FOG are being reduced due to the utilization of highly integrated approach of all the gyro components. Specifically, the ASE light source and the receivers, splitters and TIA are all incorporated in a small, robust silicon/silica platform using hybrid integration. In addition, the sensor is using an innovative new coil design and high performance miniaturized IOC that results in tenfold reduction of the bias temperature sensitivity compared to the existing FOG products. The combination of these attributes supports a smaller, lower cost, high performance and robust IRU that can serve future NASA mission needs.
