ABSTRACT:
A light emitting device, such as a light emitting diode or a laser diode. The light emitting device comprises a light emitting semiconductor active region disposed on a substrate. The substrate comprises an optical absorption coefficient below about 100 cm−1at wavelengths between 700 and 465 nm a GaN single crystal having a dislocation density of less than 104per cm2and an optical absorption coefficient below about 100 cm−1at wavelengths between 700 and 465 nm. A method of making such a light emitting device is also provided.
