Effects of polarization dependent gain and dynamic birefringence of the SOA on the performance of the ultrafast nonlinear interferometer gate
The model of ultrafast nonlinear interferometer gate accounting for the polarization dependent gain and dynamic birefringence has been developed. It is shown that these effects can lead to appearance of the satellite pulses and limit the achievable extinction ratio. The effect of dynamic birefringen...

| Summary: | The model of ultrafast nonlinear interferometer gate accounting for the polarization dependent gain and dynamic birefringence has been developed. It is shown that these effects can lead to appearance of the satellite pulses and limit the achievable extinction ratio. The effect of dynamic birefringence can be completely eliminated by proper adjustment of SOA axes but it can strongly impair the performance of the gate when the axes are misaligned. The switching window should not be set to half of a bit-period to avoid interference of the satellites of neighbor pulses. |
