Abstract:
It is shown that two mutually uncoupled microresonators in series can adequately cover the entire I-Q space and render the realization of QAM signals possible. This approach is based on the independent optimization of each microresonator for amplitude and phase modulation respectively. Generation of 16 quadrature amplitude modulation is demonstrated by means of simulation.
