Abstract
A light converting optical system employing a planar light trapping optical structure illuminated by a source of monochromatic light. The light trapping optical structure includes a photoresponsive layer including quantum dots. The photoresponsive layer is configured at a relatively low thickness and located between opposing broad-area reflective surfaces that confine and redistribute light within the light trapping structure, causing multiple transverse propagation of light through the photoresponsive layer and enhanced absorption and light conversion. The light trapping optical structure further incorporates optical elements located on a light path between the light source and the photoresponsive layer.
