Abstract :
An upgrade to standard modulation phase-shift method is shown to improve accuracy through electrical scan of the optical spectrum. Experiments have allowed the capture of fast group delay ripple of a dispersion-compensating fiber Bragg grating with only a small modification to the standard setup.
