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. The three-level NRZ signal and a synchronous optical clock signal are injected into an SOA, which acts as a nonlinear element and causes the spectrum of the input NRZ signal to be broadened due to the cross phase modulation (XPM) effect. A detuned filter is thus used to extract the specific part of the broadened spectrum to obtain three-level RZ signal. The proposed conversion can be achieved with error free at 10G baud rate.
