More and more enterprises are realizing that SOA is a reality than a myth. Information system landscape of most enterprises is heterogeneous in nature and comprises of a combination of legacy and modern systems. In many cases, applications with in an IT landscape might not be able to communicate or share data among themselves due to lack of common standards. In order to address this interoperability...
We present two types of 42.6 Gbit/s all-optical non-return-zero (NRZ) to return-zero (RZ) format converters using semiconductor optical amplifiers (SOAs). The converters are based on cross-phase modulation (XPM) and cross-polarisation modulation (XPolM) in SOAs. Both format converters produce a correctly-coded, polarity- preserved RZ signal at the output and have the flexibility of variable NRZ input...
A 42.6 Gbit/s all-optical non-return-to-zero (NRZ) to return-to-zero (RZ) format converter using a single SOA followed by an asymmetrical Mach-Zehnder interferometer is presented. The format converter generates a correctly-coded RZ signal with a controllable duty-cycle. It has the advantages of flexible input NRZ wavelength, preserved input polarity, negative bit error rate power penalty and low switching...
