Abstract :
The authors demonstrate a wavelength (de)mux that is dispersion-free and has significantly better figure-of-merit, defined as 1-dB bandwidth over 20-dB bandwidth, over existing devices. A four-channel demux has been fabricated and the figure-of-merit is 97%. A practical system application of this device has also been demonstrated.
