To heighten the sensitivity of the IFOG, one can lengthen the sensing fiber; however, this modification carries the drawback of increasing both the size and the cost of the gyroscope. Here, we introduce an IFOG architecture based on mode-division multiplexing (MDM), which shows relatively high performance levels. With the integration of MDM, the experimental results confirm a doubling of sensitivity, an improvement in angle random walk, and a reduction in bias instability fo
