Abstract
Photonic arbitrary waveform methods and generation by manipulating the phase-locked longitudinal modes of an approximately 12.4 GHz fundamentally modelocked external-cavity semiconductor laser are demonstrated. Photonically synthesized sine waves (center frequency of approximately 37.2 GHz, linewidth less than approximately 100 Hz, dynamic range approximately 50 dB at approximately 100 Hz resolution bandwidth) and complex, arbitrarily shaped optical/microwave frequency waveforms with instantaneous bandwidths up to approximately 75 GHz are shown. A WDM filter can be used to separate individual longitudinal modes of a modelocked laser. Photonic arbitrary generation occurs through the modulation of individual channels before recombining the channels, followed by amplifying the output.
