Abstract :
We experimentally demonstrate a tunable optical generation of up to 40-Gbaud 16- QAM from a QPSK signal using a variable DGD element based on vector addition between two polarization states. We also show the baud rate tunability and investigate the tolerance of 16-QAM generation to the DGD offset.
