A WAVELENGTH-MATCHING SCHEME FOR MULTIWAVELENGTH OPTICAL LINKS AND NETWORKS USING GRATING DEMULTIPLEXERS

We propose a simple and low-cost wavelength-matching scheme for multiw avelength optical links and networks using grating demultiplexers. We demonstrated that the wavelength can be matched and maintained within 0.006 nm with the reference wavelength, and thus, among all other demu ltiplexers in the links and networks.
