Abstract
A demultiplexer and a method of demultiplexing a multiplex of spatially separable multiple wavelength streams, where an incoming multiplex of multiple wavelength streams is separated into a first stream of wavelengths and a second stream of wavelengths according to at least one predetermined separation criterion. The first stream and the second stream are respectively input into a first and a second input port of a multi-input port, multi-output port frequency demultiplexer where the first stream and the second stream are separated into a first group of single wavelengths and a second group of single wavelengths respectively. The first group of single wavelengths is coupled to respective output ports and the second group of single wavelengths are coupled to respective output ports.
