Publication number: 20240079853Abstract: An electrical contact for a semiconductor device, and a method of forming an electrical contact is disclosed. The electrical contact comprises a perimeter area, an aperture located within the perimeter area and one or more electrical tracks extending from the perimeter area into the aperture. The one or more electrical tracks comprise a non-linear shape. The presence of the one or more electrical tracks within the aperture provides a means to remove, or significantly reduce, the problematic effects of current crowding within a semiconductor device in which it is employed. The electrical contacts provide particular application for semiconductor laser devices. When the electrical contact is located on an output surface of the semiconductor laser device, the condition for a diffraction pattern to be imparted onto the emission profile of the output light of the semiconductor laser device is removed, thus improving the overall beam quality of the output light.Type: ApplicationFiled: February 20, 2023Publication date: March 7, 2024Inventors: Jonathan Robert ORCHARD, David CHILDS, Richard TAYLOR

Patent number: 11710847Abstract: The use of ion-conducting materials to protect electrodes is generally described. The ion-conducting material may be in the form of a layer that is adjacent to a polymeric layer, such as a porous separator, to form a composite. At least a portion of the pores of the polymer layer may be filled or unfilled with the ion-conducting material. In some embodiments, the ion-conducting layer is sufficiently bonded to the polymer layer to prevent delamination of the layers during cycling of an electrochemical cell.Type: GrantFiled: October 18, 2021Date of Patent: July 25, 2023Assignee: Sion Power CorporationInventors: Michael G.

Patent number: 11050219Abstract: A laser device has a photonic crystal surface emitting laser (PCSEL) element. At a first lateral side of the PCSEL element, a reflector is arranged to reflect back into the PCSEL element at least a portion of light travelling out of the PCSEL element through the first lateral side of the PCSEL element. Between the first lateral side of the PCSEL element and the reflector there is interposed an electrically controllable light-transmission region configured to control the transmission of light from the PCSEL element to the reflector, based on an electrical input. Also disclosed is a method of operation of a corresponding laser device.Type: GrantFiled: May 5, 2017Date of Patent: June 29, 2021Assignee: The University Court of the University of GlasgowInventors: Richard Hogg, David Childs, Richard Taylor
