Abstract
As optical communication systems begin to fill the available bandwidth in an optical fiber by transmitting either 40 Gb/s on 200 GHz channel spacings or 10 Gb/s on 50 GHz channel spacings, the optical phase response of the components deployed in the systems will need to be carefully controlled. The dominant method for measuring this optical phase response is commonly called the modulation phase-shift method,1 and uses an amplitude modulation of a narrow-linewidth tunable-laser to measure the dispersive properties of optical devices.
