Abstract
A de-multiplexer () for separating two co-propagating modes of electromagnetic radiation includes a volume () having a path therethrough for receiving electromagnetic radiation, an input () for directing two co-propagating modes of electromagnetic radiation to be incident upon the volume, a control source () of electromagnetic radiation arranged to generate a time-dependent control field. The volume is arranged and the time-dependent control field is shaped such that, when the two co-propagating modes of electromagnetic radiation and the time-dependent control field are incident upon the volume contemporaneously, the time-dependent control field causes the volume to accept one of the two modes of electromagnetic radiation onto a mode of the volume without any parametric non-linear optical interaction taking place and to reflect or transmit the other of the two modes of electromagnetic radiation, so to spatially and/or temporally separate the two modes of electromagnetic radiation from each other.
