ABSTRACT:
A system for dynamic waveform shaping in an optical fiber comprising: the optical fiber receiving an optical waveform, the optical waveform having individual spectral lines; a plurality of fiber bragg gratings in-line on the optical fiber, each having a reflectivity wavelength corresponding to one of the spectral lines; a plurality of polarization controllers in-line on the optical fiber, each polarization controller receiving the optical waveform from a respective fiber bragg grating; a circulator for directing the optical waveform as input to the plurality of fiber bragg gratings and receiving the optical waveform as output from the plurality of fiber bragg gratings; and a polarizer in-line on the optical fiber receiving the optical waveform from the fiber bragg gratings and the polarization controllers.
