Paper Abstract

A wideband photonic RF vector modulator with novel architecture is presented and demonstrated with capability of continuous amplitude modulation and 0°-360° phase shifting. In-phase and quadrature-phase components of the output signal are used to produce 360° continuous phase shifting and optical attenuation is used to control the signal amplitude. A novel 8-tap all-optical transverse-filter implementing a Hilbert transform is proposed and demonstrated to produce 90° quadrature phase-shift for the broadband RF signal. Experimental apparatus and results for continuous vector modulation will be presented for the frequency range of 1-6 GHz.
