Abstract

An optical package is proposed comprising a carrier, an optoelectronic component, an aspheric lens, and a reflective layer. The carrier comprises electrical interconnections and the optoelectric component is arranged for emitting and/or detecting electromagnetic radiation in a specified wavelength range. Furthermore, the optoelectric component is mounted on the carrier or integrated into the carrier and electrically connected to the electric interconnections. The aspheric lens has an upper surface, a lateral surface, and a bottom surface and the bottom surface is arranged on or near the optoelectric component. The aspheric lens comprises a material which is at least transparent in the specified wavelength range. The reflective layer comprises a reflective material, wherein the reflective layer at least partly covers the lateral surface of the aspheric lens, and wherein the reflective material is at least partly reflective in the specified wavelength range.
