Abstract:
1. A light-emitting array, comprising: a plurality of light-emitting elements, wherein each of the plurality of light-emitting elements comprises a first semiconductor stack; a plurality of bridge structures connected to the plurality of light-emitting elements, wherein the plurality of light-emitting elements is spaced apart by the plurality of bridge structures, wherein each of the plurality of bridge structures comprises a second semiconductor stack which has the same epitaxial stack as the first semiconductor stack, the first semiconductor stack and the second semiconductor stack each comprises a top mirror stack having a first conductivity type, a bottom mirror stack having a second conductivity type, and an active layer formed between the top mirror stack and the bottom mirror stack; and a confinement layer with a aluminum composition higher than that of any other layer of the top mirror stack, wherein the confinement layer is formed in the first semiconductor stack and the second semiconductor stack; wherein the confinement layer in the second semiconductor stack is a continuous layer without forming any opening, and is continuously connected to the confinement layer in the first semiconductor stack.
