Abstract

An optoelectronic device for outfeed and infeed of radiation into and out of a waveguide having the waveguide disposed on a substrate and provided with a mirror for reflecting the light through the substrate. The device includes at least a plano-convex lens being integrated on a surface of the substrate lying opposite the waveguide. In one embodiment, a second substrate is secured on the first substrate and one of the substrates has a recess for receiving the lens and the second substrate can have a recess aligned with the lens for receiving an end of an optical fiber.
