Electrical contact

An electrical contact for a semiconductor device comprises a perimeter area surrounding an aperture 9, and one or more electrical tracks 14 extending from the perimeter area into the aperture. The electrical tracks have a non-linear shape, such as a spiral, curved or S-shape. The non-linear electrical tracks may reduce the effects of current crowding. The perimeter area and the electrical tracks may be formed from an electrically conductive material such as gold. The electrical contact may be used in a semiconductor laser device, such as a vertical cavity surface emitting laser (VCSEL) or a photonic crystal surface emitting laser (PCSEL). The electrical contact may be located on an output surface of the laser device. The non-linear shapes of the electrical tracks may avoid imparting a diffraction pattern onto the emission profile of the output light, which may improve the beam quality. A method of forming the electrical contact is also disclosed.
