Abstract (en)

[origin: WO9836302A1] An optical device (1) for dividing input light having a mix of wavelengths ( lambda 1 to lambda 16) into discrete output wavelength bands ( lambda 1 to lambda 16) and combining discrete wavelength bands ( lambda 1 to lambda 16) into an output of mixed wavelengths ( lambda 1 to lambda 16). The device (1) includes at least three optical wavelength selective devices (2, 3, 10) of the kind having a first port (23), a second port (25) and a third port (26) optically interconnected at least partly by one or more waveguides (18, 19). A first of the selective devices (2) has the second port (25) optically connected by waveguide to the first port (23) of a second of the devices (3) and the third port (26) optically connected by waveguide to the first port (23) of a third of the devices (10).
