Bandwidth and bit error rate performance of walk-offcompensating 1.5/1.3 µm wavelength converter

The authors demonstrate wavelength conversion from a 20 nm band near 1.5 – 1.3 µm at 5 Gbit/s using a novel nonlinear optical loop mirror that compensates for pulse walk-off. The bit error rate performance of the device at 2.5 Gbit/s is also reported.
