Abstract :
The soliton self-frequency shift (SSFS) in orthogonally polarised femtosecond soliton pulses is reported for the first time. It is shown that SSFS for orthogonally polarised solitons is approximately 1/3 of that for parallel polarised solitons. This is attributed to the orthogonal Raman term. The 2π and π dependences of the SSFS on the phase difference between the two solitons are newly obtained for parallel and orthogonal polarisations, respectively. The largest SSFS occurs in-phase under parallel polarisation
