A method of integrating a semiconductor component with a polymeric optical waveguide component, and an electro-optical device comprising an integrated structure so attainable
The invention relates to a method of fabricating an electro-optical device which comprises integrating a semiconductor component with a polymeric optical waveguide component. According to the invention, a semiconductor component obtained by epitaxial lift-off (ELO) is embedded in a waveguide device which in addition to a polymeric optical waveguide structure comprises an appropriate cavity. The invention further pertains to an integrated electro-optical device attainable by means of this ELO technique. Notably, it concerns an integrated electro-optical device in which the polymeric waveguide component and the semiconductor component are integrated on a substrate made of a different material from that of the semiconductor component, preferably a material with good heat dissipation, such as silicon. Preferably, the polymeric waveguide component comprises a polymer in which waveguide channels have been provided by bleaching.
