    摘要: Multiple wavelength source, in particular for optical communication employing a plurality of wavelength multiplexed channels, comprising a broadband light source (2) coupled to a discrete wavelength separator (3). The wavelength separator means (3) compromises cascaded refractive Bragg gratings (14, 15, 16, 17) each reflecting a discrete wavelength (&lgr;n, . . . , &lgr;3, &lgr;2, &lgr;1) to a source output (20).
