Abstract :
The intrinsic phase noise of semiconductor lasers is interferometrically converted into high levels of intensity noise by reflections at single-mode connectors and other fibre-optic components. This noise can have significant adverse impact on both direct detection and coherent transmission systems, causing bit-error-rate floors in extreme cases.
