Abstract

Array illuminators find wide applications not only as optical distributors for an array of optical devices but also as key elements for optical interconnects . We have evolved a simple and a straight - forward method to fabricate a two - dimensional integrated optic array illuminator that is capable of generating multiple twodimensional beamlets . Two identical plane holographic gratings orthogonal to each other were multiplexed on a photosensitive emulsion coated glass waveguide . On coupling a laser beam from the side opposite to the emulsion multiple parallel beams travelling normal to the surface are generated . Experimental details and results are reported.
