Abstract
An apparatus comprising at least: a first waveguide; a second waveguide; and a diffractive element. The first waveguide guides a first band of onto the diffractive element such that the first band is diffracted at an mnon-zero order over a first range of angles. The second waveguide guides a second band onto the diffractive element such that the second band is diffracted at the mnon-zero over the first range of angles. The second waveguide guides a third band onto the diffractive element such that the third band is diffracted at the nnon-zero order over the first range of angles. Wavelengths of the first band, the second band, and the third band do not overlap with each other. The morder and the norder are different from each other.
