Latest Patents
Kokou Dossou holds a patent for "Planar waveguide grating devices having controlled polarization dependent sensitivity and method of manufacturing thereof." This patent describes a method for forming diffraction gratings from grooves that feature both reflective and non-reflective facets. The design allows for a trade-off between the net reflection of Transverse Electric (TE) and Transverse Magnetic (TM) polarizations. By controlling the degree of metallization on the reflective facet and ensuring that the non-reflective sidewalls remain uncoated, the grating structure achieves improved performance. Additionally, other diffraction gratings are manufactured from trenches that are etched perpendicular to a waveguide, which are then metallized and back-filled with a refractive index-matched filling material.
