Abstract
One source of noise in optical communication systems is multipath inte rference (MPI)-intensity noise caused by multiple discrete reflections or double Rayleigh backscatter (DRB). MPI converts phase noise to int ensity noise, which can cause significant impairments in analog lightw ave systems. We have found that by dithering the laser frequency by se veral gigahertz at kilohertz frequencies this noise can be reduced. We have demonstrated this technique using a DFB laser.
