Abstract: A method of fabricating an optical lens disclosed herein includes forming a layer of a flat lens structure on a front surface of a substrate, depositing a protective metal layer on the layer of the flat lens structure and on a back surface of the substrate, wherein the protective layer includes chromium, gold, titanium, or nickel, wherein the back surface is located opposite to and away from the front surface having the layer of the flat lens structure, irradiating the protective metal layer at the front surface with a laser to form a channel (i) through the protective metal layer, (ii) through the layer of the flat lens structure and (iii) in the substrate, removing the protective metal layer at the front surface and the back surface of the substrate, and separating the layer of the flat lens structure from the substrate to obtain the optical lens, wherein the channel has a depth defined by a thickness of the substrate remaining at the channel after irradiating the protective metal layer at the front surface with the laser. The optical lens fabricated from the method is also disclosed herein.

Abstract: An illumination module for a vehicle includes first, second and third LEDs, and first, second and third masks aligned with respective ones of the first, second and third LEDs. Light emitted by the first LED that passes through the first mask is a first color and light emitted by the second LED that passes through the second mask is a second color and light emitted by the third LED that passes through the third mask is a third color. When the LEDs are electrically powered to emit light, light emitted by the LEDs passes through the respective masks to project first, second and third projected images at a ground area adjacent the vehicle, each projected image having the respective color. The projected images overlap at the ground area and, combined, establish a multi-color logo or indicia at the ground area adjacent the vehicle.

Abstract: An electrically-variable optical device includes a planar optical element (POE) and at least one electromechanical layer. The POE includes at least one optical layer. The at least one electromechanical layer is configured to spatially deform the POE to change an optical parameter of the POE. The at least one electromechanical layer may include a dielectric elastomer actuator (DEA) which includes electrodes and an elastomeric spacer between the electrodes. An electric field may be introduced between the electrodes to deform the spacer, which in turn deforms the POE.
