Abstract
An optical relay device, for relaying polychromatic light is disclosed. The device comprises: an input optical element formed in a planar substrate for receiving and redirecting the light for propagation of the light in a lateral direction within the substrate; and an output optical element formed in the substrate for receiving light propagating within the substrate and coupling the light out of the substrate. The device further comprises a reflector assembly at least partially coating opposite surfaces of the substrate for substantially reflecting light rays impinging on the reflector assembly at an angle within a first angular range, and substantially transmitting light rays of the polychromatic light impinging on the reflector assembly at an angle within a second angular range. In some embodiments of the present invention the input optical element and the output optical element are diffraction gratings having a periodic profile shaped such that at least one portion of the light is dominantly coupled into a diffraction order m satisfying |m| > 1.
