Abstract :
An integrated multichannel wavelength monitoring circuit using specially designed phased-array waveguide grating and detector arrays, which monitors all wavelength-division multiplexing channels in real-time (sixteen channels at 200-GHz spacing), has been demonstrated with /spl sim/0.02 nm accuracy.
