Efectos de dispersión a primer orden y SRS sobre un pulso con polarización circular dentro de un NOLM con fibra torcida en lazo
A theoretical analysis is presented in order to study the influence of both First Order Dispersion, and Stimulated Raman Scattering (SRS) on the transmittance of a Nonlinear Optical Loop Mirror (NOLM) made of twisted fiber with low birefringence. The system NLS equations were modified in order to in...

| Sumario: | A theoretical analysis is presented in order to study the influence of both First Order Dispersion, and Stimulated Raman Scattering (SRS) on the transmittance of a Nonlinear Optical Loop Mirror (NOLM) made of twisted fiber with low birefringence. The system NLS equations were modified in order to introduce the FOD and SRS effects, then they were solved numerically take into account the effects of first order dispersion and SRS on a circularly polarized pulse within a NOLM based on the principle of polarization’s asymmetry. The simulation results show that the first order dispersion effectis to increase the transmittance of the NOLM for pulses with input power lower than soliton power. This effect results in decrease of the nonlinear switch contrast. For input power higher than soliton power, SRS avoid the coherence between pulses. That destroys the NOLM operation. |
