Experimental verification of a very low crosstalk wavelength router construction using arrayed-waveguide grating multi/demultiplexers

A very low crosstalk N/spl times/N wavelength router construction based on 1/spl times/N AWG multi/demultiplexers has been proposed. The peak crosstalk level of -53 dB is measured in such an 8/spl times/8 wavelength router and the power penalty from the router is negligible. Rather large wavelength routing networks can be built using the wavelength router construction presented.
