Abstract
The invention relates to an AlInGaN alloy based laser diode, which uses a gallium nitride substrate. It also includes a lower cladding layer, a lower light-guiding layer-cladding, a light emitting layer, an upper light-guiding-cladding layer, an upper cladding layer, and a subcontact layer. The lower light-guiding-cladding layer and the upper light-guiding-cladding layer have a continuous, non-step-like and smooth change of indium and/or aluminum content.
