Abstract
Abstract A substrate (102) having a surface (103) with a plurality of electrical traces (106) disposed thereon is provided. A photonic device (111) is operably mounted on the electrical traces (106) of the substrate (102). An optical portion (121) having a reflective surface (118) that is embedded in the optical portion (121) for directing light to and from the working portion of the photonic device (111) is disposed on the surface (103) of the substrate (102), thereby encapsulating the photonic device (111) in the optical portion (121).
