A planar spectrograph for demultiplexing optical wavelength signals includes a monolithic substrate. The substrate has a diffraction grating etched therein. The diffraction grating is integrally formed in the subtstrate to be in operative relationship with input light to diffract and reflect the input...http://www.google.es/patents/US20030197862?utm_source=gb-gplus-sharePatente US20030197862 - MULTIMODE PLANAR SPECTROGRAPHS FOR WAVELENGTH DEMULTIPLEXING AND METHODS OF FABRICATION
