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.
