Abstract :
The Raman time constant (TR) used in the generalized nonlinear Schrodinger equation is determined experimentally at 1550 nm based on the Raman self-frequency shift in a standard single-mode fiber. The effective value of the TR as measured is found to be 3.0 fs. Detailed error analysis shows that the uncertainty in the measurement is less than ±1.0 fs. The measured value of the TR is approximately half of what is commonly used at present in theoretical simulations. Determined experimentally in this work the accurate value of TR=3.0 fs is essential in modeling pulse propagation in optical fibers
