Abstract

We experimentally demonstrate optical multiplexing of two 20 Gbit/s QPSK channels at different wavelengths onto a single 40 Gbit/s star 16 QAM channel with tunable ring ratio using cascaded fiber based nonlinear stages. The impact of QPSK channel spacing is also investigated. BER measurements confirm the effectiveness of the proposed scheme.
