Two-dimensional focusing holographic grating coupler

Two-dimensional focusing grating couplers have been produced using holographic interferometry with freely propagating wave fronts. Theoretical considerations lead to an optimized holographic arrangement. Experimental grating couplers with 2.2-μm focus-spot diameter have been achieved.
