1. A method of fabricating an optical component, the method comprising:
adhering an illumination layer to a carrier glass substrate with a release bonding layer, wherein the illumination layer includes light sources and electrical traces for activating the light sources;
overmolding a refractive polymer layer over the illumination layer;
forming a lens curvature into the refractive polymer layer to generate a lens layer, wherein the lens curvature provides optical power; and
separating the carrier glass substrate from the illumination layer and the lens layer in a debonding process.
