摘要： A III-nitride compound device which has a layer of AlInN (7) having a non-zero In content, for example acting as a current blocking layer, is described. The layer of AlInN (7) has at least aperture defined therein. The layer of AlInN (7) is grown with a small lattice-mismatch with an underlying layer, for example an underlying GaN layer, thus preventing added crystal strain in the device. By using optimised growth conditions the resistivity of the AlInN is made higher than 102 ohm·cm thus preventing current flow when used as a current blocking layer in a multilayer semiconductor device with layers having smaller resistivity. As a consequence, when the AlInN layer has an opening and is placed in a laser diode device, the resistance of the device is lower resulting in a device with better performance.

摘要： A light emitting diode device which includes at least one light emitting diode, a heat-sink chassis having a surface upon which the at least one light emitting diode is mounted, and a waveguide having one end coupled to the at least one light emitting diode for receiving light therefrom. The waveguide has another end which includes a light extraction and redistribution region, and the waveguide is configured to guide light received from the at least one light emitting diode away from the heat-sink chassis and towards the light extraction and redistribution region. The light extraction and redistribution region is configured to extract and redistribute the light from the waveguide.
