Summary:A wave optical simulator has been developed to analyze the optical characteristics of 3-D structures, including their diffraction and interference. The optical characteristics of inner-layer lens structures were studied by using this TOCCATA-Wave 3-D simulator. An inner-layer lens structure gives a better concentrated focal region and a smaller lateral shift in the focal region under oblique incident light compared with a single-lens structure. The improvement in the light-gathering power of the inner-layer lens structure was found to be remarkable when a small F-number and a large top-lens height were used.
