Abstract:
An optical device comprising:a first concave diffraction grating to reflect light from an input beam into a plurality of light waves of different wavelengths focused at spatially separate locations; a first concentrator having a first plurality of light guiding channels to transfer the plurality of light waves; a first plurality of fibers optically coupled to the first plurality of light guiding channels; an array of optical elements, wherein each of the array of optical elements has at least one input and at least one output, the at least one input of each optical element in the array being coupled to one of the first plurality of light guiding channels; a second plurality of fibers optically coupled to the at least one output of optical elements in the array; a second concentrator having a second plurality of light guiding channels, each of the second plurality of light guiding channels optically coupled to a distinct fiber in the second plurality of fibers; and a second concave diffraction grating to reflect light from the second concentrator into a single light beam focused at an output fiber.
