<p>An optical device (1) for dividing input light having a mix of wavelengths (μ1 to μ16) into discrete output wavelength bands (μ1 to μ16) and combining discrete wavelength bands (μ1 to μ16) into an output of mixed wavelengths (μ1 to μ16). 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).</p> |
