Abstract :
A 5 GHz-spaced 4200-channel demultiplexer that covers the 1.46 to 1.62 μm wavelength range of the optical frequency chain spectrum broadened by supercontinuum generation in an optical fibre is described. The demultiplexer was realised using a two-stage tandem configuration consisting of a 1 THz-spaced arrayed-waveguide grating as a primary filter and 5 GHz-spaced 288-channel AWGs as secondary filters
