Titel Inhoud "Tunable waveguide grating with a heating layer." "The present disclosure relates to an optical device including a waveguide grating. The optical device may be used as an optical cavity for a laser device, for instance, of an integrated laser device for light detection and ranging (Lidar) applications. In particular, the optical device comprises a waveguide grating for guiding light, a heating layer provided beneath or above the waveguide grating, and two or more contacts for passing a current through the heating layer, to generate heat in the heating layer. The heating layer is thermally coupled to the waveguide grating and is optically ..." "Method for differential heating of elongate nano-scaled structures" "Janusz Bogdanowicz, Wilfried Vandervorst" "The present disclosure is related to a method of fabricating a semiconductor device involving the production of at least two non-parallel nano-scaled structures on a substrate. These structures are heated to different temperatures by exposing them simultaneously to polarized light having a wavelength and polarization such that a difference in absorption of light occurs in the first and second nanostructure. In some cases the light is polarized in a plane that is parallel to one of the structures. The present disclosure may provide differential heating of semiconductor structures of different ..."
