ABSTRACT:
Optical data is processed and transmitted in a multimode transmission medium in a manner that facilitates the mitigation of interference such as that often referred to as intersymbol interference (ISI). According to an example embodiment of the present invention, a spatial light modulator is controlled to adaptively spatially filter light to be passed on a multimode transmission medium such as a multimode optical fiber.
