| Popis: | We show that spectral filtering using a fiber Bragg grating as an optical discriminator improves the performance of semiconductor optical amplifier (SOA) wavelength converters. This technique increases the operation speed and reduces the data patterning effect of SOAs for non-return-to-zero (NRZ)operation. For return-to-zero (RZ) operation the fiber grating increases extinction ratio and preserves the data polarity. We use this technique to obtain error-free wavelength conversion of NRZ data at 10 Gb s in an SOA with 6 GHz dynamic bandwidth. We also use the SOA fiber grating to convert RZ data at 10 Gb s and show that the converted pulses can propagate error free over 20,000 km in a dispersion-managed system. |
