Latest Patents

One of Schrauwen's latest patents is focused on coupling methods and systems using a taper. This invention discloses optical devices designed for coupling radiation between an optical waveguide and an external medium. In one embodiment, the optical device includes a semiconductor die with an integrated optical waveguide core and an overlying optical waveguide that features a waveguide taper and a waveguide facet. The design ensures that the overlying optical waveguide at least partially overlaps the integrated optical waveguide core, with the waveguide facet positioned between about 1 µm and 200 µm from the edge of the semiconductor die. Another embodiment of this patent describes a method that involves providing a substrate with an integrated semiconductor waveguide and forming an overlying waveguide that includes a waveguide taper and a waveguide facet. This method also includes cutting the substrate at a distance of about 1 µm and 200 µm from the waveguide facet.

Another significant patent by Schrauwen is related to an integrated photonics device that is operatively coupleable with an optical element in a first coupling direction. This device comprises an integrated photonic waveguide and a grating coupler that is designed to diffract light from the waveguide into a second coupling direction, which is different from the first. Additionally, the integrated photonics device includes a refractive element positioned adjacent to the grating coupler, which is adapted to refract the light emerging from the grating coupler in the second coupling direction back into the first coupling direction.
