Effect of Raman Slow Light on Distributed Raman Fiber Sensors

Article Preview

Abstract:

The effects of Raman slow-light on room-temperature single-mode optical fiber sensors are examined by extracting the Raman pulse-delay terms from extended nonlinear Schrodinger equation (NLSE). Numerical study shows that pulse parameters such as pulse position, frequency chirp, and envelope distortion may be greatly affected by slow light. We demonstrate a method based on pump power adjustment for compensating the slow light induced impairment.
