Paper Abstract

We propose the use of distributed Raman amplification to improve the sensitivity of fiber optic gyroscopes through the use of longer fiber coils. The performance limitations due to noise and nonlinear phase have been analyzed and we show that, even in the presence of pump and signal asymmetries, the proposed configurations allow increased sensitivity. Concretely, it is possible to achieve a 5-fold increase in fiber length (and sensitivity) compared to traditional schemes with no amplification. Potential applications include the design of highly sensitive fiber-based rotational seismometers.
