Abstract

In this paper we propose and simulate a design for an optical phased array that can produces spot sizes small enough to be used in optical trapping processes in a micro-scale. Furthermore we attempt to combat the large grating lobes that are characteristic of optical phased arrays via an optimized non-uniform spacing profile of emitter elements. Using this optimized spacing profile we are able to reduce the peak side lobe level of a 10×10 array to 60% of the central lobe. We simulate that the full width half max of the central lobe of our 10×10 non-uniformly spaced array is 23 microns which is on the order of the spot size necessary for optical trapping.
