A device for redirecting light in two dimensions (2D) includes a wavelength-tunable light source for providing light having a spectral component at a first wavelength. A 1D redirector redirects the light in a first plane. A thin waveguide is disposed in the first plane. The thin waveguide includes a slab waveguide portion coupled to the 1D redirector for propagating light redirected by the 1D redirector. The slab waveguide portion includes a wavelength-sensitive out-coupler out-coupling the light in a second plane at an angle dependent on the first wavelength. Thus, the light is redirected in two dimensions. A display device providing image in angular domain may be based on the device for redirecting light in two dimensions.
