Abstract

Interferometric noise is a problem common to many optical networks.1 Suppression techniques attempt to realize a noise spectrum that is either very broad or is translated from baseband, thereby ensuring electronic filtering at the receiver.2 Here we demonstrate a novel technique that makes use of direct modulation of DFB transmitters. Suppression is shown to result from frequency variations from bit to bit in accordance with the heating history of the chip.
