Patent ID: 7844147

Claim:
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 disposed in a serial in-line arrangement on the optical fiber, each having a reflectivity wavelength corresponding to one of the spectral lines and arranged to receive the optical waveform incoming from a first direction and reflecting at least a portion of the optical waveform in an opposing second direction; a plurality of polarization controllers disposed in a serial in-line arrangement on the optical fiber, each polarization controller receiving at least a portion of the optical waveform reflected by one or more of the fiber bragg gratings in the second direction; 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.
