Multilevel All-optical Format Conversion from NRZ Signal to RZ Signal

Not Accessible

Your library or personal account may give you access

Abstract

We propose and demonstrate a multi-level all-optical format conversion from NRZ signal to RZ signal, using a semiconductor optical amplifier (SOA) and a detuned optical filter. NRZ signal with three intensity levels can be converted to corresponding RZ signal with error free.
