Abstract
An optical device includes a plurality of optical input ports, a plurality of optical output ports, a wavelength dispersion arrangement and at least one optical beam steering arrangement. The plurality of optical input ports is configured to receive optical beams each having a plurality of wavelength components. The wavelength dispersion arrangement receives the optical beams and spatially separates each of the optical beams into a plurality of wavelengths components. The optical beam steering arrangement has a first region onto which the spatially separated wavelength components are directed and a second region onto which any subset of the plurality of wavelength components of each of the optical beams is selectively directed after the wavelength components in each of the subsets are spatially recombined with one another. The optical beam steering arrangement selectively directs each of subset of the plurality of wavelength components to a different one of the optical output ports.
