A novel scheme is proposed and experimentally demonstrated for the generation of microwaves, based on the optical frequency multiplication principle employing a polarization interferometer. Generation of 120-Mb/s 64-quadrature-amplitude-modulation microwave signals at 40 and 24 GHz and its transmission over 25 km of single-mode fiber and 4.4 km of multimode fiber, respectively, are successfully demonstrated. The scheme is robust against laser phase noise, presents tolerance against dispersion impairments in transmission, and shows high-performance stability.
