Photonic-assisted microwave frequency multiplier based on nonlinear polarization rotation.

A photonic-assisted microwave frequency multiplier (MFM) based on the Kerr shutter is proposed and demonstrated. In this MFM, the nonlinear polarization rotation in the high nonlinear optical fiber is used for the first time to implement the light-controlled optical-carrier-suppressed modulation. The frequency-doubled microwave signal with the frequency up to 144 GHz is generated. The results of the experiment are in accordance with the theoretical prediction.
