Abstract:
1. A photonic waveform generator, comprising: an input port for receiving an optical signal; a pulse shaper coupled to the input port and configured to Fourier transform the optical signal and apply a pre-distortion waveform onto optical spectrum of the optical signal resulting in a shaped optical signal having both optical amplitude and optical phase spectral shaping; a dispersive pulse stretcher coupled to the pulse shaper and configured to provide a frequency dependent delay which disperses the shaped optical signal; an optical-to-electrical converter coupled to the dispersive pulse stretcher and configured to convert an optical input corresponding to the dispersed shaped optical signal to an electrical output; and an output port coupled to the optical-to-electrical converter and configured to output an electrical signal corresponding to the electrical output, the pre-distortion waveform of the transformed optical signal removes distortion of the electrical signal that exists in the absence of the pre-distortion waveform caused by violation of far field limitation between the optical signal and the electrical signal, where the shaped optical signal having both optical amplitude and optical phase spectral shaping is given by A where A where where a where A where ψ
